Have a look at the uStepper S32, when my mechaduino's died that's what I replaced them with. It's got a nice TMC5130 and can support higher voltages directly.
Actually my newest board will integrate a Trinamic TMC2209 module for low-powered motors, and as you said, it does accommodate UART. I believe I have the UART connected on the PCB, but I am planning on running it in step and direction mode for now. I left myself some options on this board in the (likely) event that part of it doesnt work!
I'm no SLA printerist... but I recon if you did your prints at a jaunty angle and not all orthographical like, they might not suck so much. (to the film!) less area in contact and whatnot.
I print at SUCH jaunty angles. Lol that was one of the earlier things I learned about the process, I kept getting prints stuck on the film, so I looked into it and sure enough, jaunty angles are the ticket.
Ah, the turn it on.. "its alive! ..Oh wait that should be working" moment of a project... you feel your heart sink as the thought of unspecificed hours of fault finding stretches before you...but its okay your doggo supervisor is clearly on the case
There's also the glowing hope and optimism when you don't see smoke, only for it to be torn away when there is no hum from the motor ... It's a very emotional experience! My dog Suzy mostly specializes in final inspection, so I'll make sure I present it to her when it works!
@@TabletopMachineShop The volume level is OK compared to the video but that type of sound just sounds horrible when the volume is near max on headphones lol
It's super cool seeing this project come together. I can tell there's been a ton of work behind the scenes to get to this point, let alone documenting it and putting videos together. Great job!
Thanks a lot! I've certainly been putting a ton of time into it, but so much of that time just doesn't make good footage (unless people swearing quietly at their screen is a genre!)
Look into mks makerbase servo hybrid steppers for baller on a budget servos. Its just a bolt on board and magnet that turns a basic stepper into a hybrid stepper.
I think I've seen those at some point, they look really familiar.. It looks like it would work in a step/direction configuration pretty nicely. Once the Mechaduino died, I sort of decided to just go all-in on something readily available and easily scalable -- I'm sure i would just blow up an MKS servo eventually as well :P
@@TabletopMachineShop I have a bolt on cnc conversion I am working on for atlas/craftsman lathes. I went hard and got a masso G3 touch to run it. Uses NEMA 34 12Nm steppers because I want to be able to turn a hex.
