Quotebengele Hoping that someone who is better at electronics can verify what I am going to do. I am trying to follow Tom's Guide on setting up auto bed leveling 3D printing guides: Setting up auto bed tramming leveling tilt compensation! I am going to just use the open terminals on the power supply to get 12v input and ground. It looks to me like the pin closest to the edge of the ramps board

QuoteHairLikeFrodo I'm just wondering what you guys have your vref pots on your stepper drivers set at. Mine are the standard .35v and .45v for the Y axis. I'm still getting that strange diagonal pattern. Mine is set to the voltages recommended in the new Folger tech manual. .35 .50 .35 .35 I believe. Are your bearing holders on the tray tight? Or the belt in line?

Download latest marlin from GitHub. Try compiling see if you have errors.

Re: Folger Prusa i3 Kit from ebay - 11 years ago

That's the wrong configuration h file if you are using the latest Marlins firmware. That's why you are having issues. You need to downloads the official marlin firmware and update it with your values from the golfer tech config h file, not just copy and paste which it looks like you have done.

QuoteNlh205 So I have finally had a few successful prints using the white abs from folgertech. So when I ran out I decided I would try out a spool of the pla i bought from seacans.ca. After running about 6 inches of it through my extruder, the extruder started clicking. It was the extruder trying to force the pla down through the barrel. So it ended up getting jammed and i had to clean it out, bu

Quotekonto89 What firmware did you use? I can't remember the name, however since then I have found the reason the Master Marling Firmware didn't work. WIth my Machine the MAX Endstops were always in a triggered state (You can check this with M119) even though they were not being used. Because of the this the logic behind the auto bed level doens't work and it just probes in one location instead

However I did run into problems getting aut bed level to work on the Marlin firmware.

QuoteHairLikeFrodo I fixed my issue. It was just a bad ramps board. I swapped it with my old printer and it worked perfectly. Did you get it from Folger Tech? I also had a faulty RAMPs board from them. The PINs for the Y end stops didn't work. Took me forver to work out what the issues was.

Re: Folger Prusa i3 Kit from ebay - 11 years ago

Yes, thats right. You should try the latest Marlin Firmware from here. Marlin Firmware At least then you can rule out a firmware issue.

Which firmware are you using? Have you tried flashing a new version?

by parksie - Prusa i3 and variants

Re: Folger Prusa i3 Kit from ebay - 11 years ago

Have you checked the voltage to the stepper drivers? If that is fine, I would say it could be a firmware or RAMPS issue. Have you tired pronterface and Repetier Host?

Re: Servo is causing connection faliure - 11 years ago

Quotejrcaster Make sure your servo is wired properly. There is a difference between JR, Futaba, and Airtronics wired servo's. Also you never mentioned which servo you are using. If it wasn't wired correctly. Then M402 wouldn't retract it right?

Auto bed level arm not retracting - 11 years ago

I have just got my auto bed level working, however I need to manually add a M402 to the GCODE to make it retract before printing. Is this normal? Or should it be retracting itself post G28?

Re: Auto Bed Leveling Servo not responding (M280 P0 S80) - 11 years ago

Ok, The issue was the voltage pull from the steppers was too much for the RAMPS board and caused it to crash. External power source now works fine.

Re: Mendel Heated bed low Temps - 11 years ago

Also, can you up check you power supply and make sure it is over 12V, I adjusted mine to 12.6 and addeda head sink to the ceramic on the RAMPS board. Made a huge difference. I now get to 110 is about 20-25 minutes. Before it was close to and sometimes over 1 hour.

Re: Servo is causing connection faliure - 11 years ago

Quote3dkarma Not enough power from the RAMPS board to run the servo. You'll need to power the servo separately. Ah ok. That makes sense. Others don't seem to have the same problem. Is there something I can do to increase power to RAMPS 1.4 board? Or would a different servo have lower power requirements?
