Re: Help with correct vRef - 9 years ago
Hey Thanks for your reply. I ended up going with 60% of max on the x and y. 90% of max on the Z (because its driving 2 motors so its more like 45%.) And 75% of max on the E which is a geared nema direct dirve. Everything seems to be ok now. I guess it wasn't overheating just severally underdriven. I was able to do 2 prints 1.5hrs long with no issues. Thanks for your helpby zerocool5878 - Stepper Motors, Servo Motors, DC Motors
Help with correct vRef - 9 years ago
Back story is I have had my printer for few years and I was told not to worry about setting it with a meter just tune it to where it doesn't skip steps and leave it. I have had nothing but issues with my extruder where the hobbed gear slips I think maybe due to the extruder being too hot causing the slip. It is fine if its an 30min print but any longer its it will slip for sure. I have ramps 1.4by zerocool5878 - Stepper Motors, Servo Motors, DC Motors

Thanks for the info. I think this will be used on my current reprap and right from the get-go on my next machineby zerocool5878 - Stepper Motors, Servo Motors, DC Motors
Re: Y skipping - 13 years ago
Ramps are underneath. I think i may have solved the problem. I am almost positive that the molex for my y was loose. (Probably from vibration) After slightly spreading the pins on the ramps and reinstalling the molex to a tighter fit I was able to print just like I was before. I really wish that they were made with locking molex connectors instead of plain loose header types. if it happens againby zerocool5878 - Stepper Motors, Servo Motors, DC Motors
Y skipping - 13 years ago
so tonight while printing my Y axis started grinding/skipping after about an hour into a print. The last time this happened was when i first build the printer and i was told to up the current of the trimmer by 1/8 turn and it never did it again until today. And i have printed for many 6+ hour days with no issues. I have a 40mm fan blowing across the ramps and the drivers have heat sinks on them.by zerocool5878 - Stepper Motors, Servo Motors, DC Motors
