Re: How do diagnose RUMBA board not moving extruder motor
Did you check the Rumba board for cold solder joints or broken traces?
View ArticleRe: How do diagnose RUMBA board not moving extruder motor
Well the board is not new, Id be surprised if at this point any broken traces (without moving the board) or cold points do appear (there are several fans near it). Is that even possible? Extruder was...
View ArticleRe: Wich stepper motor for MKS TMC2100?
Quoteo_lampe I'm currently using 0.9° steppers rated 2.4A with the TMC drivers on my CoreXY (300x200 bed). It's not a perfect combination, but my hotend carrier and the Y-gantry are not too heavy. I...

Its a SMD board, its dead/damaged, throw it out (unless you have the skills to do smd rework) Its most likely either a dead mega chip or dead stepper drivers... which, does it mater?, you can't fix...

Thanks, Dust. How is that test script supposed to be executed? Cheers.

You load it into the arduino ide. Compile it, and upload to your hardware Its replacement firmware but it just moves the the steppers, and turns on mosfet. its not smart in any way... NB This will...

Hello all, These Animatics motors are stepper motors (NEMA23) that include controller, encoder and IO all in the same package. Apparently they are used in CNC and others. I got my hands on a bunch of...

Trade them in for some traditional steppers/drivers and whatelse you need. Maybe someone can use them as spare for an existing machine.

Hi all, I'm writing this message because I am desperate. I built a cartesian printer and have a serious problem with steppers. All is OK except that. Here's my problem : When I connect one stepper to...

Yeah, I'll try getting rid of them on ebay. They are quite expensive when new, but a bit of a niche! The first to go will hopefully pay my Duet Wifi! Cheers

Hi, I found the problem :) I don't know why but I had to invert all the endstop into Marlin. Hope this can help some peoples. Thanks

Hi, I'm new of Marlin firmware but I use arduino for other projects. Can someone explain to me the limit of 10KHz for the timer1 used by the stepper module to generete the step pulses? If I need to...

the MKS TMC2100 with the single bank of green header pins came in this morning. Can confirm that it is as shown on the detail sample photo, CFG1 bridge is missing. will attempt to solder soon.

wellllll... i wouldn't bother buying the MKS version of these stepper drivers. with the smallest tip available from Weller and a decent soldering iron, good solder, and a 600x microscope, modifying...

I don't even know what to believe anymore about these drivers.Some users say they have the clones working with jumping the CFG-1 to GND, no mention of the solder pad on the bottom. others say remove...

I did manage to find some information on these drivers. [attachment 92681 lv8729stepperdriverinfo.docx] I've just got 4 of these, attached two to my corexy x and y axes. set 1/64th microstepping using...
View ArticleRe: MKS LV8729 , a 128 µStep Driver // Any test?
So yes cooler running both at the drivers and the motors than tmc2100, quieter than A4988s but not as much. Oddly they seem quieter at 1/32 certainly a huge amount quieter than drv8825. I'm running my...
View ArticleRe: MKS LV8729 , a 128 µStep Driver // Any test?
Also found this info related to LV8729 drviers [www.thanksbuyer.com] This suggests that the driver automatically goes to half current when there has been no step pulse for 0.5 seconds, this would...
