Re: Working on a Raspberry Pi shield for DLP 3d printers

ciclopez: Thanks for the info regarding TMC429. It seems that this chip is what I was looking for. Already ordered 1pcs in SOP24 package for prototyping and 2pcs in QFN32 package. I would probably prefer QFN32 for production as only this version offers 2 switch inputs per all 3 steppers. Do you hav...

Re: Working on a Raspberry Pi shield for DLP 3d printers

Nice to see other people working on similar projects, it looks very promising :) Sorry, I don't know any chip that integrates multiple stepper drivers + controller all in one. If you are looking for a motion controller alone to use with your Pololu stepper driver modules, I started my project using ...

Re: Working on a Raspberry Pi shield for DLP 3d printers

I wanted to show you some images as a quick update about this project. The hardware seems fully functional but still needs a lot of software development because I decided to use a new Trinamic chip, the TMC5130 instead of TMC260 + TMC429. As soon as I have some real printing tests I will upload a vi...

Re: Working on a Raspberry Pi shield for DLP 3d printers

@ciclopez: Have you finished your project? How is it going now? Hi, and welcome! Glad to hear there are people interested in this project :) I'm still in the process of designing the PCB, unfortunately I can't work full time on this project, I'm doing it on my spare time. Anyway I hope to have a wo...

Re: Working on a Raspberry Pi shield for DLP 3d printers

The first prototype I made uses a Trinamic TMC260 ;) this driver is awesome, the current of the motor is easily configurable by the user in software, and the driver adjusts the current depending on the load of the motor. Another cool feature is that you can have 1/256th microstepping with a 1/16th m...

Working on a Raspberry Pi shield for DLP 3d printers

Hi, I have been following this forum since I decided to build a DLP 3d printer and the first thing I missed was an electronic board that could handle the printing process by it's own, without a PC like almost any FDM 3d printer. I wanted to make my own board and I have some programming skills but I ...
