Re: MKS LV8729 , a 128 µStep Driver // Any test?
Hi, i want to share my experience and i hope my English will be enough. i buy a lot of TMC2100, from a lot of different suppliers. I finally found in watterott the right one. White PCB all the times...

That's very useful information. Might be a good idea to post it on some of the other threads which were more focused on tmc2100.

View ArticleWhere'd the PWM control of my cooling fan go?
This may have been going on for some time as the Anycubic which I'm using has the cooling fan hidden on the effector's back side. But I've just noticed that it's no longer responding to On/Off/Speed...

Thank you for your reply. Yes I've tried several. One thing I've come across while Googling the trouble though said that brushless fans are iffy as to whether or not they'll respond to PWM control...
View ArticleRe: Where'd the PWM control of my cooling fan go?
Even if it doesn't like PWM, it should still run when you select maximum speed. Perhaps the cable has failed, or the fan output on the controller board? Or have you uploaded new firmware, which...

What kind of motors are you using? What sort of guide rails and bearings? How big is the mechanism? How heavy is the X axis? If things are misaligned, the motors will struggle to move the mechanism....

Hi There are no problems with the mechanism, Everything moves easily. It is an CoreXY with 3 mini Wheels on all Y-zaxle and 4 Wheels on X-axle. Nema 17. The problem is that in idle the motors temp is...
View ArticleRe: Stepper motors miss stepps
If the mechanism moves easily and the motors are slipping, the motor torque is too low for the speeds/jerk/acceleration settings you are using. Increasing the motor current can get you a little more...

You have a 12V motor. Not good, especially if you are using a 12V supply. You want to get lower inductance motors- look for motors rated for about 2A at 1-3V. The motor drivers control the average...
