Re: Quality issues when printing white filament - 11 years ago
Did you do a calibration print and adjusted your slicer for the new fillament? It could be that you are extruding too much or too litle. I always use this method:by Draob - Printing
Re: Can anyone identify this on my hotend? - 11 years ago
If hou buy ABS, first try natural or white abs, as black ABS usually has a lot of recycled (contaminated) materials in it. When you buy black ABS, buy it from a reputable source. But even then I find printing with black ABS challinging. I even had my glass bed cracked twice because adhesion was so good, and warping so strong.by Draob - Printing
Re: Auto bed level probing disconnecting printer - 11 years ago
Just for anyone having the same issue, and finds this post: This is most likely because of a "brownout" of the 5 volts suplying power to the arduino. Since there is no 5 volt regulator on the RAMPS board, all 5 volt power is supplied by the arduino's 5 volt regulator. Drawi g too much current (with the servo) can cause the voltage to drop too much causing the arduino to reset.by Draob - General
Re: I'm stuck configuring my COREXY end stops - 11 years ago
With coreXY the belts cross over at the back. I don't see this with your setup, don't know if that is o.k. (No experience with these kinds of setups)by Draob - CoreXY Machines
Re: Prusa i3 auto leveling - 11 years ago
I have an I3 with auto bed leveling and with a hall sensor used as z-probe. It retracts the probe when it moves to the bed because the magnet is attracted to another one on top of the probe. Thus however will cause a short trigger of the hall sensor. If marlin would stop when the z-end stop is triggered then this shouldn't work.by Draob - General
Re: First print, tuning advice. - 11 years ago
What were you trrying to print? Also to check if your steps per mm are about correct you can use prusa's calculator.by Draob - General Mendel Topics
Re: Bed Auto Leveling.. check this out - 11 years ago
I am planning to base it off this design: Rostock Z-Probe Automatic Bed Leveling with Hall-Effect Only thing is that you need to pull out the probe tip manually, but since you need to remove prints anyway and prepare the bed this is not a big problem for me. If you do auto bed leveling with G29 a couple of times in a row you can see how much the mechanical switch deviates everytime. Some printby Draob - General Mendel Topics
Re: Bed Auto Leveling.. check this out - 11 years ago
I have a problem with auto leveling. It is working and I can print (although I want to design a hall probe for the i3 rework for more precision/repeatability) Problem is that with G28 it homes X and Y against the MIN endstops that I have and it probes the bed height with the probe. After G29 and probing the whole bed, going to 0 with G1 X0 Y0 does not return them to the endstops but about 50 mmby Draob - General Mendel Topics
Re: Bed Auto Leveling.. check this out - 11 years ago
I meant the menu on the LCD if you have one connected. It would be great to add it, since you can also adjust the Z-offset from the LCD. What I mean is that according to the marlin code list G28 means home al axis. But with auto bed leveling it doesn't do that, it homes X and Y and Z still stays from the printbed. Because G28 is different when you don't have auto bed leveling and when you doby Draob - General Mendel Topics
Re: Bed Auto Leveling.. check this out - 11 years ago
I would like to see an "Probe bed level" menu item in the marlin menu which does G29. Also with the "clasic" endstop situation I had, choosing "Auto home" homed all my axis and put the nozzle in the home position. Because I have auto bed leveling now and safe z homing, it stays in the middle of the bed. I would like it to go to the home position with the auto home command in the menu.by Draob - General Mendel Topics
Re: Bed Auto Leveling.. check this out - 11 years ago
Finally got bed levelling working. Problem is that when you have the EEPROM turned on in the configuration, the Z-height offset of the probe is not taken over from the Configuration.h file. You need to go into the menu and go to CONTROL -> MOTION -> Z Offset. Another thing is that this value is positive while you would expect it to be the same as in the Configuration.h (negative).by Draob - General Mendel Topics
Combine slicer and cad design for better mechanical designs - 12 years ago
Hello all, I am quite new to the reprap community, and there is one thing I have been thinking about. Right now the 3D design program is separate from the software that decides how the part get actually made (the slicer). Wouldn't it be better if you could combine these two somehow so you could have some more influence on how the part is made. Why this would be useful: - if you have a part andby Draob - 3D Design tools
Re: Ramps 1.4 & PG35L voltage - 12 years ago
The stepper driver is taking care of this, you only have to make sure that the current is set correctly.by Draob - RAMPS Electronics
Re: LCD only works with USB connected - 12 years ago
Had the same problem after a short on the 5V rail coming from the arduino. Please check the output of the voltage regulator on the arduino.by Draob - RAMPS Electronics
