Printing issues ...
Re: Prusa i3 stopping mid print*video* - 10 years ago
Thanks for all input. I tried disabeling stuff, starting with the E stepper motor. Suddenly it printed again. I connected the stepper and it fails. I started to fiddle with the stepper drivers adjusting the ports, after a while I realized I had no clue of their position so I started all over and put the all to a minimum and increased until all axles moved without missing steps. All drivers enby ice - Printing

Quotechris33 Is your usb cable anywhere near a power cable that can cause it printing without USB makes the same thing. The new PSU did not help. will try disabling steppers and extruder nextby ice - Printing
Re: Prusa i3 stopping mid print*video* - 10 years ago
QuoteShaneH Is that a psu, or a battery charger? Can't find any specs on it, and some sites are listing these under the category of battery charger(???) It's a switched power supply 12-30volts, 30A. I just orderd a new 650W computer PSU to se if that helps. I started out with a 500W computer unit capable of 20A and it was running very well for a long time, as my problems showed up I changed tby ice - Printing

QuoteShaneH Wow...sounds like it's being powered with a jackhammer! Has it always been that noisy? And just between you and me....you should really do something with your wiring. You could have a weak joint somewhere in that mess, and when it gets to a certain z height, and the wires pull in a particular way, could be causing your issue. I would run a print and start moving wires. If it cutsby ice - Printing

When it fails the 5V drops to 3.3v if that are any hint. Measured on the servo output on RAMPS. Printing without the bed gives a little longer print time before it freezes. My power supply of the day is a 1kW 30A capable unit that are not dropping in voltage. it keeps 12.0v at all times. But I don't know if it filters out EMC as good as a computer PSU?! does it matter?by ice - Printing

Quotewaitaki Have you tried printing from your laptop rather than via SD card to see if the problem remains? Same problems usb printing too.by ice - Printing
Re: Prusa i3 stopping mid print*video* - 10 years ago
Quotechris33 are you cooling your stepper drivers Thanks for you kind reply Only the passive cooling, small heat sinks. Have been working for a long while though and I did try with a new ramps with new drivers too. However I got some ideas from Collin at Makerfarm and we noticed that when I unplugged the USB cable the LCD went blank. So I changed to the new arduino using my old stock ramps. Nby ice - Printing
Prusa i3 stopping mid print*video* - 10 years ago
Hi guys, I need some help. My printer have been working flawless for a long time. Suddenly it started acting strange. Stopping mid print and the steppers did not answer until a reboot of the printer. I tried: New arduino new ramps with new drivers re flash firmware with auto bed leveling re flash stock firmware (makerfarm) disable bed leveling servo new PSU re install computer software new comby ice - Printing

Problem solved! I found that useing Z-lift my Z stopped moving up. It retracts as it should but always return to layer 1 level. With Z-lift se to zero Im back on track printing again...by ice - Slic3r

Re: New Slic3r 0.9.10b - 11 years ago
I just got my makerfarm 8" i3 running and made a couple of prints that turned out very well. I updated to slic3r 0.9.10b and ran in to problems with too much filament feed. I tried to adjust this for a whole evening before noticing that the Z was not moving up for the new layer. Any one else got these problems? I did try both repetier and ponterface with the same results, my old sliced gcode sby ice - Slic3r
