I got my E3D non-Bowden set up with my Bowden system and printed a part in 3MM black PLA from Monoprice last night. It has some small sections that slow the print to 5 mm/s. No jams. I will say I was worried based on my "manual" testing (meaning pushing filament through with my hand) that I would have jamming issues, but the torque of the Wades extruder manages it with ease. I did have to up theby jaydmdigital - General
It's not clear what temperature you are printing at (bed temp too), what material, what speed, feeds, what cooling, and what retract. Those all play a part.by jaydmdigital - General Mendel Topics
Wait, "when I disconnect the RAMPS board it connects no problem". That tells me there is something amiss with your RAMPS. It's a common issue to have plugged your endstops so that Ground and VCC are getting shorted instead of the signal wire. Double check your corrections. You should be able to connect with the RAMPS in place. If you want, take a photo of your RAMPS wiring so I can do a visual inby jaydmdigital - General Mendel Topics
So just using the Arduino IDE, are you able to connect to your Arduino on com3 at a lower baud rate? Did you upload any new firmware? Check your configuration.h file to see what baud rate you have set.by jaydmdigital - General Mendel Topics
Can you post a new video of your machine printing. Denote the speeds you are using for the perimeters and infill. An acceleration of 3000 is very quick and the only time I see it on my machine is when it does an X/Y travel which I have at 400mm/s.by jaydmdigital - General Mendel Topics
configuration.h looks fine. Have you compiled and uploaded?by jaydmdigital - General Mendel Topics
Not directly familiar with Melzi but found this: from the on the wiki. You might need to post your configuration.h so we can confirm your current settings (assuming you have changed and uploaded the Marlin firmware to your Melzi board.by jaydmdigital - General Mendel Topics
Another option RUMBA up to 6 motor driver with easy micro stepping setup (micro switches) which can be used for: TRIPLE extruder DUAL Z driver and DUAL extruder ... 5x temperature ADC connectors for thermistors: e.g. 3x extruder thermistor + 1x heated bed thermistor + 1x chamber thermistor 5x PWM capable power mosfet outputs (3 with voltage selector for MainPower/12V): e.g. 3x (MainPower) extrudby jaydmdigital - General Mendel Topics
Ok, Sailfish is your firmware, not Marlin. I am not up on Sailfish but I was under the impression is was for Makerbots. From this thread: http://forums.reprap.org/read.php?4,161124,174248 "I just came accross the sailfish posting on Thingiverse and decided to look into it a bit. I found a "lively" debate about the topic on google groups. As far as I can tell, sailfish and marlin both use the sby jaydmdigital - General Mendel Topics
For marlin, acceleration is set in the configuration.h file. look at lines 363, 365 and 366 in the linked file to know what to look for in your configuration.h file. So make sure you do a calibration of your machine (Google calibration reprap or check Richrap's blog for some examples). The top infill looks a bit sparse, did you measure your filament and plug it into Slic3r?by jaydmdigital - General Mendel Topics
You guys seen this thread: ? He is using which has 6 outputs. Prusa Mendels do slave the two Z motors together on one channel so it does work, but can't say if it'll work on Cube mechanics not know how well they run.by jaydmdigital - General Mendel Topics
That's easy, your nozzle tip is too far away on your first layer. Lower your Z home limit so that the nozzle is touching the surface at 0. -Jayby jaydmdigital - General Mendel Topics
pronterface is host software. I am talking about either sprinter or marlin firmware. Means you will need Arduino to change the code, recompile and upload to the Arduino Mega.by jaydmdigital - General Mendel Topics

So assuming you ahve read this: and visited ... what part has you confused exactly? Also, since you ahve a kit, there shoudl be a known set of values for the X, Y, Z, and E motors already. Also, here is a video review of calibrating your MakerFarm i3 and be sure to watch his review of the Magmaby jaydmdigital - General Mendel Topics
Holy smokes look at the length of filament for that print "7978352.5131mm"! That's not right. Look in your configuration.h and tell us how many steps per mm you have configured for your extruder. Did you do a calibration? -Jayby jaydmdigital - General Mendel Topics
Tells me that either your thermistor is broken, a broken wire or a poor connection. Use a mutimeter and measure the resistance is the temperature probe leads to confirm.by jaydmdigital - General Mendel Topics
So your plan is to use the existing mechanicals of the CubeX and perform brain surgery on it? You will need some technical specs on the stepper motors (degrees per step, amperage, hopefully bipolar windings). I would assume the CubeX has endstops...are they mechanical switches, opto-interrupters, hall effect? What about the extruder motor, and what voltage is your hotend? Does the thermistor matcby jaydmdigital - General Mendel Topics
Are you able to attach the gcode to a reply. I want to use Repetier-host to view the output and see if it's a slicer issue or something else. I personally don't see any benefit to using 250Kbaud over the 115.2Kbaud so you could try lowering to that as a easy first step too. In your slicer what speed do you have the top layer set to (assuming Slic3r v.9 or higher)? -Jayby jaydmdigital - General Mendel Topics
If you leave them 3mm, then you will need to use nuts because there won't be enough material to thread. Or you could use M4's but then you's need to drill out the printed parts.by jaydmdigital - General Mendel Topics
Just tried the Monoprice.com PLA (I ahve tried both black and white and they also have red) and it's as good as the ultimachine but only $26 for 1Kg. I have also used PLA from Amazon.com called Jet - PLA. It worked fine too but costs $36 per Kg. Just another opinion. -Jayby jaydmdigital - General Mendel Topics
The X carriage is not on upside down. This is the first mendel also called the Sells Mendel. Here is a photo of my old Sells: Your extruder will mount across those two holes like so: Unfortunately I did not have a Wades at the time, that's a MakerGear geared extruder and hotend. -Jayby jaydmdigital - General Mendel Topics
Repsnapper sends a M code to the Arduino FW to turn off/on the heater. Thus, if you check the communication log you would see the M106 or M107 sent. Now, if the FW "ignores" (in quotes because I don't know the specific FW so I don't know the logic it uses if ther eis no temperature probe) it then that's not a Repsnapper bug. And it's Prusa.by jaydmdigital - RAMPS Electronics
I don't have to shut down Repsnapper, but yes on the Mega2560 I have noticed the same thing. Really only an issue if I am working on the configuration.h in FW and then testing the print out to get things dialed in. Confirm your baud in configuration.h -Jayby jaydmdigital - RAMPS Electronics
I looked at this too. But it was the Cool model in Skeinforge that I played with. There is a Minimum Layer Time that you can shrink but you should use active cooling if you do this. I am able to print at 65mm/s even for small parts like pulleys. -Jayby jaydmdigital - RAMPS Electronics
The new hardware endstop require additional pin configurations to enable the built in pull up resistors in the ATMega. The opto endstops had a pull up resistor as part of the circuit board so this extra configuration was not required. Since I started with Repsnapper that did not support G28 (home all) I learned to click each axis home button. Unfortunately, my version of Repsnapper does have aby jaydmdigital - RAMPS Electronics
Ultimately the root cause is that the torque required to move the filament is greater than the motor can supply at the requested speed. The faster a stepper spins, the less torque it has. to brnrd's point you can reduce the torque by increasing the temperature and thus the flow. Also loo to see if there is added friction from your filament spool. -Jayby jaydmdigital - Reprappers
Since PLA flows at 180C I use 200C for the fist layer. PLA holds heat very well and thus I think your issue is too high a temp. Try 200C and see how you do. I als agree that the first layer should be a bit less than your layer height. -Jayby jaydmdigital - Reprappers
