V1 Engineering's Piper

V1 Engineering's Piper I have decided to build the [url=https://www.v1engineering.com/assembly/]V1 Engineering Piper.[/url] First C-Foot 3D Print in ABS looks promising, with ABS shrinkage the ID for the Feet is 23.37 the conduit measurement is 23.5. This means that very little finish work will need to be done in order to assemble the Piper 3D Printer. I setup the Printer nozzle to 228C with a bed temperature of 98C, first layer print speed 40 all remaining layers 76 percent. This calculates to 8.5mm^3 per secound. With a layer height of .28 an infill at 40% the First model for my new 3D Printer/CNC looks great unfinished. Using the parts cooling fan at 40% full speed (102/256). Room temp 72.7 Heated enclosure left side 37.87C Enclosure Vent Fans speed 60% [attachment 111137 C-Foot.jpg] I have 3D Printer all the smaller parts and a couple of the larger parts with very good luck using ABS filament. The more I print with the ABS at the higher bed temperature, noticed that the 3mm aluminum bed is bowing. The perimeter of the bed is lower while the center is getting higher and higher. The auto bed leveling is somewhat taking care of it. But I wander how much it will take before parts will get affected by the bowing an become Unusable. Want to try an heat the bed while placing a heavy object center bed, then allow it too cool with weight remaining in the center. Hoping that this action might allow the bed to return to a more level state. It appears may need a Borosilicate Glass Build Plate. Not looking forward to this as my Proximity sensors will not allow for leveling a Borosilicate Glass Build Plate. https://reprap.org/forum/read.php?131,852148,852148#msg-852148 Tue, 10 Mar 2026 17:49:58 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?131,852148,862284#msg-862284 Re: V1 Engineering's Piper https://reprap.org/forum/read.php?131,852148,862284#msg-862284 To do this I will need more Time and money to add an additional stepper motor. Then configure the firmware as needed.

The reason is simple, want an extruder to possibly 3D Print a few larger models when needed.
I know that the XY steppers can run in series and may eventually end up doing it this way. Though would prefer to use 6 steppers drivers.]]> Roberts_Clif CNC Routers, Mills, and Hybrid RepRapping Mon, 11 Nov 2019 08:07:58 -0500 https://reprap.org/forum/read.php?131,852148,856587#msg-856587 Re: V1 Engineering's Piper https://reprap.org/forum/read.php?131,852148,856587#msg-856587

Vacuum Duct
Frame Supports // Frame is not as sturdy as I would like it.
Cable chains
Power Supply case
Arduino, Ramps Case
ect, ect ect.

Some of the thinner printed ABS models are quite fragile, they resemble older plastic degraded by weather.
Will need to reprint them, maybe this time in PLA.

Good thing is that the Dewalt will be showing up today an will be able to actually cut something.
Will start out with something weak like a piece of pink insulation.
Then work up to some softwoods that I have laying around
Then ending with hardwoods to get an ideal how fast the cuter will work, an some basic settings for EstlCam tool setups.
And speaking of tools I will be needing a source of good cutting tools, you know something that will not have to be replaced often.

At this time I have given some thought as to the size of the hot bed 400mm X 600mm. Will now need to see if this can become a reality Now.

I can start with two silicone heaters 300mm X 400mm on fairly sturdy piece of aluminum plate, though how thick should it be, do not want to go crazy an go unreasonably thick.
I want it thicker than my Hictop beds that has warped, Any help here would be appreciated.

I may even forgo the Heaters and use a non-heated bed for a while, still do not want to under size the bed plate for when I do upgrade to a heated bed.]]> Roberts_Clif CNC Routers, Mills, and Hybrid RepRapping Tue, 09 Jul 2019 07:37:07 -0400 https://reprap.org/forum/read.php?131,852148,856237#msg-856237 Re: V1 Engineering's Piper https://reprap.org/forum/read.php?131,852148,856237#msg-856237

I have been hanging out on the Octoprint lists for a while after I ran into some problems and it has been discovered that for a while Octoprint serial port I/O to printer controllers has been causing print quality issues. Many experiments have been run that show SD card prints to be of higher quality than serial port Octoprints. Some kind of serial port latency and/or throughput bottlenecks are causing print stalling and jerkiness that result in in less-than-perfect surface quality on print jobs.
So, it may be that the time-lapse is contributing to the surface quality degradation, but it probably isn't all of it...

Pity, I really like Octoprint. I will be trying a Duet Maestro on my main printer next (someone had a sale :). I am hoping to be able to print directly to a Duet from Simplify3D and CURA.

I have noted that Raspberry Pi 4 has been released, though they only will sell you one and they sell out in minutes. would one of these make a difference with Gigabit Ethernet and USB3.

I have noted a distinctive difference between the SD card Print and the OctoLapse Print textures.

Noted: in the Photos above the model on right was printed with the SD Card While Model on the left within OctoPrint's Octolapse.
You will note a distinct texture difference. Will print another model using same ABS filament with SD card to verify if smoothness returns.

Well I blew the AMS1117-05 in a heartbeat so today I replace the AMS1117-05 with a DC-DC Step Down Buck Converter 1.5V 3V 5V 9V 12V 3A Adjustable Module this was set to the 5V jumper.

[attachment 111959 DC-DCdownconverter.jpg]

My question is why did this switch made by BigTree-Tech.com for maker bot kill the AMS1117-05, tested the switch it operated correctly.
My 2nd question is now that Arduino has a 3amp 5volt supply should be able to run a LCD 12864 Smart Controller correct.

I must be right at the max current limit for the regulator because when I power it on with the new regulator is now works correctly.]]> Roberts_Clif CNC Routers, Mills, and Hybrid RepRapping Mon, 08 Jul 2019 11:19:08 -0400 https://reprap.org/forum/read.php?131,852148,855911#msg-855911 Re: V1 Engineering's Piper https://reprap.org/forum/read.php?131,852148,855911#msg-855911 I went off the paper on the feet

Have not ordered a pair of Full Graphics controllers for my newly purchased Arduino Mega 2560 R3's and Ramps.
Though it is still on my list of parts to be ordered.

My next modification will be to remove the AMS1117-5.0 regulator on the Arduino and replace it with this same DC-DC Step Down Buck Converter. This time instead of setting it to a variable voltage will be using the set 5 volt jumper pin on the converter.

This will allow for the additional power requirements needed to operate the Full Graphics controller I will be using. All power supplied from a single 24vdc power source from the Ramps 1.6 controller power pins...]]> Roberts_Clif CNC Routers, Mills, and Hybrid RepRapping Tue, 02 Jul 2019 13:08:02 -0400 https://reprap.org/forum/read.php?131,852148,855752#msg-855752 Re: V1 Engineering's Piper https://reprap.org/forum/read.php?131,852148,855752#msg-855752 I am now powering my ramps with a 20amp 24volt power supply.

I removed D1 replacing it with the output of the buck converter I soldered the diode anode side to IN (24vdc) and soldered the
diode cathode side to VO leaving the GND terminal to be soldered to the Ramps ground Power Connector.

[attachment 111828 DCtoDcBuck.jpg]

I did not install a DC-DC Step Down Buck Converter Module set to 5volts to replace the AMS1117-5.0 at this time
This was on my agenda so I could use the full graphics controller that draws to much current from the AMS1117-5.0.

Will do this after the Full graphics controller arrives.]]> Roberts_Clif CNC Routers, Mills, and Hybrid RepRapping Sat, 29 Jun 2019 18:55:19 -0400 https://reprap.org/forum/read.php?131,852148,855679#msg-855679 Re: V1 Engineering's Piper https://reprap.org/forum/read.php?131,852148,855679#msg-855679 With ~6mm above the bed then lowered the Tool plate 6mm on all four corners an dead center the platform.
Being really close to the main floor platform here, took my filler gauges out and began measuring the height.
After comparing all five locations, deturmined that the MPCNC that I just built is measuring 0.06mm from level.

Knew I was being careful making my EMT Conduit cuts, but never ever expected that I was being this precise.
This is going to be is enough to mount a Large Aluminum Plate above the floor Platform, heated or not heated.
For 3D Printing large 508 X 762 X 292mm Models WoW! this is going to take a long, long, long, time to print.

Have you decided on a spindle yet? Will it be switched on/off through the software? I was thinking of powering a relay through the fan connector on the RAMPS board to control the power to the spindle motor. What do you think?

I'm not sure of that's a good idea. Would you be able to use PWM for the spindle speed that way?

I was thinking more along the lines of using it to just switch a relay on and off. The spindle would get its power through the relay contacts. Similar to powering a Heat bed through a relay. Or I could just use a toggle switch and manually switch it. I was going to get a 120 volt AC spindle.]]> Shank man CNC Routers, Mills, and Hybrid RepRapping Wed, 26 Jun 2019 12:40:01 -0400 https://reprap.org/forum/read.php?131,852148,855639#msg-855639 Re: V1 Engineering's Piper https://reprap.org/forum/read.php?131,852148,855639#msg-855639

Use a Ac Programmable Dimmer Module for Arduino
Or
Use a DeWalt DW660 or a 750W Variable Speed Grinding Rotary Tool.

Have not 3D Printed any holders yet so I duct taped a purple Sharpe to the Tool holder, this was for just a quick test.
Tried to turn Sena1 into a G-Code. Followed all the instructions still, Have not yet figured out how to create my G-code so I used the Crown on [www.v1engineering.com]

It is a little weak on the steppers V-Ref though for testing I will not worry about this until after I 3D Print a power supply case designed for it. Thinking about designing a case for the Controller and Ramps 1.6 on the back of the tool carriage, routing the cables via a series of cable chains, then will only have the power supply wires to route from the rear of the main floor to the controllers.

Will have to think about how to gain another stepper motor driver to run an extruder maybe.

Are you going to use end stops and implement the auto squaring function?

Not at this time, will need to learn before I start working with auto squaring function.

In fact when I did my first test I accidental grabbed the Z Stepper motor cable and connected it to Y2 (E1) and the Z-Axis moved smoothly across and back.
Only noticed when out of the corner of my eye an thought I saw the Z-Axis turning then tried again and knew I had hooked up the Z-Stepper motor incorrectly to Y2 (E1).
Then connected the correct Stepper motor and tried again and visually saw no differences in the Y axis movement. I know it had probably lagged a little though moved smoothly.

I will be testing all software I can find starting with Estlcam V11. If you have any thoughts and a demo download or free software post will try and find the ones I like best...
I was hoping to test the controller using a pen or pencil on paper to see how the stock Marlin firmware works, at first with simple one layer drawings.
Then graduate to more complex sketches.

This is why I chose the A4988 Driver modules, I can still add the DVR8825 with the double diode TL smoother if this fails to give clean steps at 1/16.

If you're going for professional results, why do you keep messing with toy electronics? Those failing/failed motor driver modules are trying to tell you something. Get a Smoothie-board or a Duet (not a junky clone from China) and be done with it.

Actually this is my First Arduino / Ramps 1.6 configuration, and it was my own mistakes that caused the damage not the fault of the controller or the drivers modules...
An the Arduino / Ramps 1.6 configuration are well suited to do this kind of controller functions.

As for the big picture even this is far out of my budget, am extremely lucky. Bet Smoothie or Duet would not reduce the cost for those who cannot afford retail.
So I am very thankful just to have anything in this field of technology, as you so nicely pointed out to me (" junky clone from China ") in my possession.
Thank you China so very much for creating, cloning open source or what ever you did to produce these high quality affordable products for all of us.

You will not believe this but the first test out, blew the Adruino's AMS1117-5 regulator.
So ordered the new regulators and of course you can get 10 for the price of one so purchased a lot of 10.
After replacing the regulator tried the test again an every thing worked except the Stepper motors.

Troubleshooting high and low could not do any thing to get them working again.
Did what anyone who wanted the system up and running would do, Ordered the whole shooting match again.
Arduino Mega with Ramps 1.6 and five A4988 stepper motor drivers.

Today I received the new electronics and started to test, an wouldn't you know it the thing will do run.
After more troubleshooting I found a single A4988 stepper motor driver module was shorted out.
Removed the shorted driver and tested as much as possible with only 4 Driver modules.
These boards are working, Now I decided to test the other electronics parts.
And found that all original drivers modules are dead, the shorted one making 6 dead stepper motor modules.
Did determined that the Arduino and Ramps 1.6 survived the AMS1117-5 regulator destruction twice.

Today I ordered ten stepper motor driver modules.

Advancing through the Build level and waiting for more parts, thought I would post a couple photos.

[attachment 111777 2273.jpg]

[attachment 111778 Image1.jpg]

Finally decide on a build size 508 X 762 X 292mm (20inches X 30inches X 11.5 inches)

Need to re-examine the firmware the LCD displays only about half what I believe should be displayed.
Will Start with large sheets of paper to draw a complex sketch using a pencil, would like to see it do something.
Then will draw a set of calibrations drawings or rulers all over the paper.

Need to start thinking about printing some cable chains to get the MPCNC looking professional.

Note:
The driver modules that were used in the firmware build were DRV8825 this has 32steps for the same settings, as the A4988 drivers that were purchased for My MPCNC which have 16 steps.
Do not know if this will make much difference as long as the firmware is changed to accommodate the 16step driver modules.]]> Roberts_Clif CNC Routers, Mills, and Hybrid RepRapping Mon, 24 Jun 2019 13:08:39 -0400 https://reprap.org/forum/read.php?131,852148,855369#msg-855369 Re: V1 Engineering's Piper https://reprap.org/forum/read.php?131,852148,855369#msg-855369

Looking at your circuit diagram (which is very nice by the way), we generally go by a rough rule of thumb in the development department of 2200uf per amp for the smoothing caps and add plenty of HF decoupling/filtering too when designing new PSU's, but that's for high-spec PSU's for industrial and school use etc.

Well Thank you.
Have never pushed it to the max while connected to a scope to see the ripple voltage, though knew I needed larger filter capacitors.
I heard the noise on my old CB when I was testing the supply, but did not have the capacitors available at that time.

Will be needing a variable supply more and more with my 3D Printers an will be doing some modification in the future. Testing for low ripple with max currents will be an important test.
I had also labeled the Power as 1.7 - 30 VDC, though it will never reach 30volts, the transformer is only rated for 24 volts center tapped at 10 amps.]]> Roberts_Clif CNC Routers, Mills, and Hybrid RepRapping Thu, 20 Jun 2019 23:53:35 -0400 https://reprap.org/forum/read.php?131,852148,854830#msg-854830 Re: V1 Engineering's Piper https://reprap.org/forum/read.php?131,852148,854830#msg-854830

Considering all these bearings pressing and trying to roll on two galvanized steel tubes (what about their alignment ?), no wonder you need a lot of torque !

From all the videos I have watched of others who have built the V1 Engineering MPCNC before me and or similar like the Piper or LowRider CNC this is not a problem.

After assembling the main carriage I find that the Z-Axis moves smoothly, so smoothly in fact that one could barely tell any differences between the smooth rods in a 3D Printer.
Simply speaking I found that the EMT conduits I have a smooth machined surface lines along their lengths if aligned with the bearing this will allow for a smoother travel.
So if I mark the bearing travels on the conduits an polish the linear surface to allow an even smoother travel should never have any problems.
An Extra Brace is warranted to help the EMT conduit from warping with the weight of the Spindle motors or Larger Engraver motors.

The main reason for the higher torque stepper motors, is when you want to cut wood or aluminum you will find that the stronger steppers will Allow for faster more accurate cutting...
Myself I want to CNC circuits boards, 3D Printer Wood Case Frames and 3D print larger Models might even try a laser, though was told that the LED lasers have a really short lifespan.]]> Roberts_Clif CNC Routers, Mills, and Hybrid RepRapping Sat, 08 Jun 2019 13:29:09 -0400
