Hi mark love what you doing with this project it seems a fantastic option to advanced 3D printing couple of quick questions if you don't mind as I'm very interested in acquiring your panda bored to build a upgraded Delta FL son Q 5
a) first question have you seen the REPRAP firmware that people are using to access DWC https://github.com/gloomyandy/RepRapFirmware Unsure if you think this is interesting but it seems to have some advantages over Marlin and could work really well to bring more users/sales to your RPI 3D controller approach, let me know what you think ?
b) second question is over closed loop stepper motors is there a way they can be used with the Panda controller board as again it could be another way you could help advance the field of 3D printing to provide very much higher accuracy and control than many competitors approaches. not to mention lower power/switching needs on the controller PCB/hat itself ? https://www.biqu.equipment/products/bigtreetech-s42a-42-stepper-motor-closed-loop-driver-board-with-oled-display
Ales, yes agreed :-) actually have installed printer in a cabinet now so kids and cats cant intrude ! more interestingly loving what mark is doing with Panda PI and now supporting Klipper, the front ends available now with klipper screen would be fantastic and using the DSI screen connecter on an RPI4 would be so easy to integrate. GitHub - jordanruthe/KlipperScreen: GUI for Klipper
Mark have you looked at the Fluidd or Mainsail UI ? as this could elevate your whole solution to something way above almost any other offerings available !!
Hi Daniel, calm down please, Not sure I'm always asking, but to address why i'm interested my cat went into a 2 day print and ruined it, something which closed loop steppers may address, secondly im progagly more interested in something like an addressable stepper ie the contral board sends it an absolute or relative address and the stepper takes care of the motion to get there, if the intelligence is in the stepper and therefore the driver power electronics as well, then the control board becomes much more of a less noisy, high current ,etc environment and approach's like mark's panda pi have a lot more potential, finally if the resolution and stealthchop, baby stepping, uart/vs voltage pot issues that people have with different stepper drivers goes away eg tmc 5160 compatibility ( or lack of is an example ) , to me that's progress, happy to be corrected or convinced if you prefer the staus quo or believe some other way is superior ,
Why are you always asking about closed loop steppers?
They work with every board with replaceable stepper drivers.
Thanks for those good advice about next generation，I know a little about reprap firmware.but have used this close loop module and very interest it,have learn that code,but not clear how to help advance the field of 3D printing.
