Print just stopped, motor/stepper driver issue?
Just testing out my printer rebuild and I started with the xyz calibration cube from thingiverse. Must have got somewhere between 4th and 6th layer when the printer just stopped. No errors on LCD or...

Overtemp protection of a driver? They usually start again after a few seconds, but then the print is messed up already. Next time, just wait and see. If the whole print stopped, it might be the...

To check for over temp, would a quick feel of the heatsink be a good indicator? I am running TMC2100 on all motors except extruder as that wants more current so I am using DRV8825. I did check that...

Did the motors all stop at the same time? If so, it's most probably not a driver problem. The MKS gen has the same crappy 5V regulator, IIRC. Not sure about the polyfuses, tho. Graphic LCDs can cause...

So I had a go again last night. Printed the cube again but this time it printed all the way. Print looked bad so I then calibrated the esteps. Went to print the cube again and it froze again at about...

Quoteo_lampe There are drivers with 1/128 microstepping, but AFAIK they require rewriting/reflashing the firmware ( Marlin on Ramps? ). Not recommended for beginners. Why not stick to A4988? I've got...

That motor is rated at 1A per phase, low enough to be driven by an A4988.

I unplugged the LCD and printed via octopi. Print worked fine

Quotedc42 That motor is rated at 1A per phase, low enough to be driven by an A4988. Ok, thankyou. If I want to achieve it on my MK8, I have to make a reduction?

I have a 1.2A stepper on my MK8 and it works reliable, just keep the retraction speed below 80mm/s.

Hello all, I use a RAMPS 1.4 + Arduino MEGA. I have 2 power supply in my setup 12V and 24V (for the heatbed). I would like to power my TMC2208 drivers with 24V. Is it possible to remove the VMOT and...
View ArticleRe: Powering TMC2208 with external 24V PSU
Yes, most just put the pins in the driver facing up vs down but you should also have caps across the vmot/gnd pins to smooth out power spikes, as the ones on the ramps arent being used if you do this.

Thanks for your answer! Yes, you're right for capacitors. What do you recommend? 100uF 50V?

Whats up with the numbers at treshhold and [mm/s]? Well I dont know why it shouldn´t work with another register/timer?
View ArticleRe: TMC2130 on MKS GEN 1.4, high pitch noise only on y axis
Right, I missed that. It seems the Y-driver didn't communicate over SPI and hasn't received it's setup. This could be related to the different register, but I'm no expert.

View ArticleRe: TMC2130 on MKS GEN 1.4, high pitch noise only on y axis
Seems to me, the register got overwritten by a FW-routine. You have to find a different pin for Y_CS. Preferably ALL Y-pin assignments should be in the same register, but we don't know, since MKS is...
