Re: Using a level shifter and a TB6600 with smoothie - 4 years ago

I needed a bunch of 5 volt sources and the limit switches were all being used I solved this by installing a couple DC - DC converters on my 24 volt power supply I have 24 volts, 12 volts and 5 volt supplies now

Using a level shifter and a TB6600 with smoothie - 4 years ago

I finally got some time to get back on my picker machine build Here's what I need to do I am setting up a dual axis Y and open drain is not working for me with my smoothie board My smoothie board motor driver outputs 3.3 volts My TB6600 stepper driver requires 5 volts So I purchased a few Logic leveler boards to step up the 3.3v to 5v I have never used them before and I want to make sure I a

Mystery solved M4 was dead on this smoothie board I ended up using an external driver paralleled to the Y axis (M2) on the smoothie board Got it all running perfectly I shot a video of the twin Y axis in motion Here’s the youtube video link of my build

How to setup Smoothie config for 5 steppers - 4 years ago

My version 1.1 - 5 axis smoothie board will be controlling a Pick and Place machine I have one X axis ball screw - M1 I have two Y axis ball screws - M2 and M4 m2 and M4 will be slaved together I have one Z axis ball screw - M3 I have one left over axis M5, that will have a small stepper attached later to operate a component feeder device I have already jumpered the pins below on the smooth

Re: Strings between printed objects - 8 years ago

I finally had time to mess with the printer again I increased the retraction from 2mm to 4mm and printed the 5 objects again They came out way better with the extra retraction Thanks for the help

Re: Strings between printed objects - 8 years ago

I am thinking that it is now warmer in my shop than during the winter and the PLA starts off warmer I noticed that the printer is coming up to operating temp very quickly right now compared to a month ago I have not had time to check the retraction settings yet Hopefully in the next couple days Thanks for all the help

I will try increasing the 2mm retraction length and see what happens What about the minimum travel setting? Hard for me to wrap my mind around that setting

Strings between printed objects - 8 years ago

This is a new problem that I did not have last time I printed multiple objects (see the pic) See the pla strings between the 5 objects It's like the extractor is still extracting as it moves to each object I don't know if it's the new 1.75mm PLA I just installed I measured it at 1.75mm and set Slic3r for 1.75mm Or the new Slic3r I just installed (1.2.9.a) Can anyone tell me how to fix this?

Re: V-Slot its like T-Slot with built in linear rails! - 10 years ago

I am still confused as to how the set screw rides on the washer and adjust the bearing play How big is the washer and how big is the set screw?

Re: V-Slot its like T-Slot with built in linear rails! - 10 years ago

I am all set on my printer. I am not using V-Slot, I use 20mm T-slot rails My V-slot idea was just an experiment to see what I could come up with Your idea sounds fun, are you going to make one and test it? I custom made UHWM bearings for my printer that ride on 20mm T-slot rails They slide like glass and are very smooth See the attached image

Slic3r 1.0.0RC1, multiple parts are staggered - 10 years ago

I did not see a topic here or on Github regarding this I added 3 of the same parts.stl files to Slic3r Then pulled them into horizontal alignment, side by side using the alignment lines that surround the 3 parts They appear to be perfectly aligned when viewing the Plater display When printing, the middle part is shifted up a bit and not aligned horizontally with the two outside parts. This was

Re: New release Slic3r 1.0.0RC1, bug with Mach3/EMC - 10 years ago

Thanks for the updated link I see why I missed the topic now, the subject was not what I expected That's great news that it has been fixed testing the output code now with the replaced character With the E replaced with an A, Mach3 is printing happily as we speak

Re: New release Slic3r 1.0.0RC1, bug with Mach3/EMC - 10 years ago

Quotejustcurious done I looked on github but could not find this issue reported Has it been reported? Don't want to do iot if it has already been done. Looking at the Gcode again this morning it looks like the code line that contain an E just need to be replaced with an A Example before G1 F3000.000 A22.38037 G0 X-9.524 Y4.803 F3000.000 G1 E23.38037 F3000.000 G1 X-9.946 Y4.782 A23.39474 F30

Re: New release Slic3r 1.0.0RC1, bug with Mach3/EMC - 10 years ago

Having an issue here also with Mach3 and Slic3r 1.0.0RC1 Slic3r is creating lines of Gcode that have the letter E, Like the middle line shown below This was not an issue with previous versions of Slic3r Mach3 will not run the line with the E code shown below And the E code appears many times through the Gcode file G0 X-1.736 Y1.788 F4200.000 G1 E75.61461 F3000.000 G1 X-5.322 Y-1.798 A75.78876

Re: V-Slot its like T-Slot with built in linear rails! - 11 years ago

yeah, they would have to circulate is what I am thinking. And the balls need to be smaller in order to keep the body size small. Not much can be done with the current design. It was just a fun idea I had

Re: 3D printer build #2 - 11 years ago

Hi, yes, I designed the machine from scratch. Many of the parts were designed in CAD and printed on my 1st printer or cut on my CNC machine After building one from scratch and using it for a while, I had a good idea how to improve many aspects of the design. I took my time and planned design number two over a couple months I wasn't in any hurry and so I took my time and thought out every aspe

Re: V-Slot its like T-Slot with built in linear rails! - 11 years ago

Thanks Mark, I'll send it out today The combo of all the items it takes to make a T slot linear bearing gets really expensive You need the aluminum housing, 3 x Pads, 6 x screws and several shims Your V-slot rails should make it much cheaper for people

Re: V-Slot its like T-Slot with built in linear rails! - 11 years ago

You are welcome to have the one I made, just let me know where and who to send it to You sent me the V-slot material which was very nice of you and so I am returning the favor. If you can find UHMW balls, give it a go. I could only find Delrin at Mcmaster or maybe I found UHMW balls and they were too expensive Can't remember because I ordered the balls a long time ago and just got around to usin

Re: V-Slot its like T-Slot with built in linear rails! - 11 years ago

Yo mark, I finally had some time to mess with the ball idea in order to create a much smaller bearing block 1st problem is you can not use metal ball bearings against aluminum 2nd problem is that the balls will not rotate unless they are able to circulate out the end, around in a circle and come back in the other end. This is how high end linear bearings work. The balls can make a complete cir
