"Unwanted dental work" 🤣🤣

Otherwise known as 'summer teeth'.

These videos are both very insightful and entertaining. Thank you 👍👍😎👍👍. I look forward to every episode

[@rickpalechuk4411]

I'm looking forward to the new nut you will be making. Thanks for sharing Cheers

[@Dellpodder]

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!

[@TabletopMachineShop]

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!)

[@oakmanindustries]

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.

[@TabletopMachineShop]

Very interesting, it does look good! I'll have to try one out some day.

[@mattinkel7342]

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

[@TabletopMachineShop]

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!

[@unpopular_mechanics]

Trinamic makes many chips/drivers/integrated motors that accept UART, might not help now.

[@TabletopMachineShop]

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!

Thank you. Part 4 đâu

[@MF175mp]

My ears died from the intro. Had headphones pretty loud

[@TabletopMachineShop]

Sorry to hear that! Is the intro audio messed up or were your headphones just higher than you though?

[@MF175mp]

@@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

[@chrisj4570g]

Love this series dude. 👊

[@TabletopMachineShop]

Thanks, I'm really glad to hear it!

[@Wobblybob2004]

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.

[@TabletopMachineShop]

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.

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.

[@TabletopMachineShop]

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

[@Eluderatnight]

@@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.

[@TheMetalButcher]

Cool. See you in 2027!

[@TabletopMachineShop]

Never! Momentum!

[@steamfan7147]

"Have the right fasteners for a project" I'm sorry, but that's simply not possible.

[@TabletopMachineShop]

Its like they can hear you and adjust their lengths accordingly!
