Re: Totally lost control of RUMBA....due to a Stepper??
OK i'll reword it... It may have killed each driver I have connected its wires onto. Question is HOW? And...HOW can I check if its the motor the faulty one or the wiring up to it that has a short or...

I'm extremely new to 3D printing but do have a working knowledge. I am running RAMPS 1.4 with Repetier firmware and absolutely nothing will make my stepper motors move. I bought a new controller and a...

Many things are needed for movement 12v on the 12v 5amp power input on the ramps is essential (not 5v, as many have accidentally done) Having some sort of working stepper driver modules plugged into...

How do diagnose RUMBA board not moving extruder motor
There comes the day a printer stops extruding and after a brief research I notice the extruder motor is not spining. This is what I've found so far: - X, Y, Z axis move flawless. - Taking measurements...

One further test... if you plug the X motor into the E0 connector, does it move? However, I think this may actually be caused by software interlock? If the hot-end temperature is too low or too high,...

No, i disabled "Cold extrusion prevention" in Marlin, so Im covered there. And no, X motor won't spin either in the Ex connectors.
View ArticleRe: How do diagnose RUMBA board not moving extruder motor
OK. There's no hardware reason why the extruder motors won't turn. So I still think it's a software problem. Marlin is working since the other motors work, so I think Marlin is intentionally stopping...

Yeah Im using Octoprint to monitor and enable motors and terminal window shows no heating issues as I disabled them on Marlin straight. When in a printer I get a MAXTEMP or any other M999 error, as...

Wasnt there a setting to FIRST ERASE the whole contents of AT2560 before reflashing? For my own sanity's sake!!!

I use "erase Eeprom" sample program in the Eprom folder of ArduinoIDE. Also don't forget to send "M502 & M500 " after you reflashed firmware to make marlin read the new parameters ( M502 ) and...

View ArticleTMC2100 (SilentStepStick) for Mightyboard?
Can I use the TMC2100 on a Mightyboard if I reconfigure the pins? Will the microstepping work and still be using the silent mode (stealthChop)? I had one of my drivers fail and wondering if I can make...
View ArticleRe: TMC2100 (SilentStepStick) for Mightyboard?
The pin assignment of the mightyboard socket is flipped. You could use almost any other pololu-stepstick compatible driver IF you are able to solder the pins in reversed direction. With the TMCs you...

Re: Microstepping and steppers in serie skipping (tmc2100)
QuoteWurstnase If you buying a TMC2100 from MKS you must solder the small pad. When you don't solder that small pad [attachment 85591 addon.jpg] the pin has no connection to the chip. So your soldered...
View ArticleRe: Microstepping and steppers in serie skipping (tmc2100)
According to the picture the CFG1 pad isn't bridged. Only CFG6/Enable is bridged. If you have to solder the wire too, depends on the mainboard. Ramps for example has a pull down resistor on MS1 and...
View ArticleRe: Microstepping and steppers in serie skipping (tmc2100)
I'm using an MKS Gen 1.4 which is basically RAMPS/Arduino together. So I would remove all the jumpers underneath the stepper driver socket headers and then bridge CFG1 pads, and bridge CFG1 to GND...
