Re: How many independent printheads are possible on one CoreXY? - 7 years ago
Quotedc42 Its looks to me that your diagrams show a regular CoreXY system plus two additional carriages using MarkForged-style kinematics, with all 3 carriages running on the same X gantry. If so, then the generalised Core kinematics in RRF will support that. But I've no idea how well the mechanics would work in practice. Thanks again, David. I'll start the drawings and see how can I squeeze theby Djrema - CoreXY Machines

Quotedc42 We've supported CoreXYU in RepRapFirmware for quite a long time. But I recently added "generalised Core Kinematics" to RepRapFirmware, which means that it can support any machine architecture for which the motion of each axis is a linear combination of the motion of each motor. So you can have as many independent heads as you like, as long as you can design the belt system, and the totaby Djrema - CoreXY Machines

Would that do the trick for 3 independent extruders?by Djrema - CoreXY Machines

Thanks Billi3. Tested on 1N5408 and worked. Eliminated 95% of the noise. There is still some, but barely noticeable - That doesn't make me willing to kill myself any more. Appreciate that.by Djrema - Controllers

A few pages back someone else reported problems with optic sensors and I think they found a solution. Worth to dig it.by Djrema - Controllers

Quotew3drk If anyone in the states want one, I'm selling my SBASE v1.2. It's been modded with stable oscillators (I'm the one who discovered the initial issue), and the DRV8825s are forced into fast decay mode to allow the use of low inductance steppers with 24v, so no need to mess with diodes. In my opinion mixed decay on the DRV8825 is useless... I was using this board on a 24v Kossel 250 wiby Djrema - Controllers
