Yes, both have firmware that supports CoreXY. I support the CoreXY mode in Duet firmware, see [github.com].

Yep, they are the right ones. I can swap the already crimped wires over to the empty housings to give me the 4 wires. The tails are only a few inches long so ill have to solder longer wiring to them....
View ArticleRe: technical issue on paralleling 4 z-azis stepper motors
QuoteNoobMan ... The 4 motors in series would make a 6.68ohms coil and the inductance would be 4 times of a single motor, so you probably "really" need 24v to make the Z axis able to move practically,...

Thanks for confirming that! Now I know what to order.

I am upgrading from a 12V power supply to a 24V power supply on my RUMBA system, and have a 24V E3D and heated bed. I use Repetier, and have tested the hot end and heated bed at 24V, no issues. I have...

That a lot with both advice, very in deep and detailing. However, about using AC power for extra size of hotbed. I would like to know the connect method of physical device. Now I only experience one...
View ArticleRe: technical issue on paralleling 4 z-azis stepper motors
To control an AC mains power heatbed, you use a zero-crossing DC-AC SSR (e.g. SSR-10DA or SSR-25DA), with the output side connected in series with the heater, and the input side connected to the...

Okay, update on the troubleshooting for this problem. First, some info: 1) The motors and wiring on this printer (Mendel90 config) have worked with a Sanguinololu 12V system previously. 2) The motors...
View ArticleRe: RUMBA/A4988s w/24V result in motors working erratically
Next update.... The wiring was okay - I think. I adjusted the max acceleration and jerk values in the Marlin firmware downward, and now the motors seem to operate normally - in one direction. They...
View ArticleRe: RUMBA/A4988s w/24V result in motors working erratically
The one-way behavior was due to some error (not yet determined) with the endstops. Taking the endstops off the board, the motion behavior is normal. So, looks like the main culprit was setting...
