So no one as any idea of what is going on here ? My guess is that there is a failure in the stepper+hotend power circuit, but where this failure come from, ramps ? PSU ? Don't know what to do to troubleshoot so any help would be great.by Repier37 - General
Yes I have. If I understand correctly the overtemp protection, the print should go on after a while waiting, and the hot end would still be heating. Am I wrong ?by Repier37 - General
Hello, I have a problem on my Rostock with ramps. It was printing fine but I wanted to change the end effector (the platform) and since my print are stopping mid-print. The symptoms are : Stepper are disable (I can move the paltform by hand). The hotend is not heating anymore. The heatbed is fine. The commands are sent form repetier to the printer On the LCD everything keeps updating (position,by Repier37 - General

Yes, they have, and I think that's why the shift was oscillating. The screw was just loose enough to allow a movement on the flat part but wasn't loose enough to allow a complete rotation of the pulley.by Repier37 - Delta Machines
So, as it's seems that the problem was mechanical, I've run a print with high acceleration to accentuate the problem (or to brake the printer). I've put some marker on my pulley and my stepper axis to check any displacement between them. And there was a displacement. I've tightened my pulley again, run another print, it was ok at first and then I saw a displacement again. The screw was getting lby Repier37 - Delta Machines
Thanks for your help. I am using LM8UU on inox rod. It's quite a "standard" rostock, I have just made a few changes on the wood frame, but as I have been able to make a correct vertical print a few weeks ago I think my frame is ok. On the 3 tower, when there is a change in the carriage direction I can see the belt turning a bit on itself (something like 5° maybe). If this is making you think ofby Repier37 - Delta Machines
Ok, great informations !! Seems to be a way more accurate calibration method I'll try that ASAP and will keep you informedby Repier37 - Delta Machines
I am using ramps 1.4 + repetier firmware 0.92 My acceleration settings are : Acceleration : 50mm/s² Travel acceleration : 60mm/s² max jerk : 20mm/s I think these are quit low already don't you think ? I've calibrated the stepper current using this guide : and raise it a bit after (1/8 turn)by Repier37 - Delta Machines
Hi everyone, As you can see on the picture attached, i have a problem with my rostock. The part is supposed to be a cylinder, but you can notice that at some point, the layer start shifting a bit, and then coming back to the correct position. This issue is happening at each print, on different part, always in the same direction (the shift seems to happen opposit to my X tower), so I think it'sby Repier37 - Delta Machines

QuoteDjDemonD No I don't mean DC power cables they produce very little EMI, I mean mains voltage power cables are to be avoided. Good to know. But the answer is no. But I found another usb cable, not shieldied either, but shorter (1m vs 3m). and ... IT WORKED. Like a charm... After all, that was just the thing I eliminate at first. Anyway, thanks a lot !!!by Repier37 - General
I had a look and didn't see anything obvious. The only thing might be : #define min_software_endstops true // If true, axis won't move to coordinates less than HOME_POS. #define max_software_endstops false // If true, axis won't move to coordinates greater than the defined lengths below. I was using inverted false-true value when I was using marlin on my rostock. But I guess that your X motorby Repier37 - Delta Machines
The firmware configuration in your link is a bit short and is speaking about X and Z axis config, but not about the Y axis, so might be something to look for. Could your send your configuration.h so we can check if we see something strange?by Repier37 - Delta Machines
I would check those line in the firmware : // For Inverting Stepper Enable Pins (Active Low) use 0, Non Inverting (Active High) use 1 #define X_ENABLE_ON 0 #define Y_ENABLE_ON 0 #define Z_ENABLE_ON 0 #define E_ENABLE_ON 0 // For all extruders And that the #define Y_ENABLE_ON is set to the same value (0 or 1) as the others Wich electronic do you have ?by Repier37 - Delta Machines
Well... No. In fact as it's working on my laptop, qith the same cable, I have guessed that it couldn't come from the cable. However I might be wrong. What do you think ? I don't have another cable right now, that's why I didn't test that solution. Edit : for the usb/power proximity, I have tried my best but, on ramps, the usb cable is right under the power cables...by Repier37 - General
Hi, I have a problem with my serial port. I have a rostock with ramps 1.4 + GEN7 extension board (rewire to the ramps) and a mega 2560 clone with the ch340 chip. My baudrate is 115200. I use repetier firmware and repetier host. When I connect my desktop computer to the printer everything is fine, I can control the printer perfectly. But when I start a print, in less than a minute I have a bunchby Repier37 - General
