    Hi Sumner
    Great work on your turntable and controls!!! If I may ask why did you use the tb6600 driver instead of an A4988 etc?

    I'm sure one could use any number of drivers. This was my first experience with stepper motors and drivers. I found a video on the 6600 and also found a sketch that I understood enough that I could use it and modify it. That eased making the jump into something new.

    I also wanted the highest number of micro steps that I could find within my price range. The 6600 will do 6400 and some that I looked at wouldn't go that high. Saying that I can't remember now if I'm stepping at 3200 or 6400. I'm not at home so can't check. I see I should add that to the documentation. I see I did put in that the amps is set to 1 amp.

    I saw others like what you posted that probably would of worked but did like the fact the 6600 didn't need to be mounted in a socket that then needed mounting. It has its own terminal strip for the wiring (made that simpler). At $12 and since I only needed one felt that it wasn't that much more than the others considering what it offered.

    I'd recommend using whichever one you are comfortable with,

    I kinda figured that the ease of mounting and wiring made you use the 6600. I have been using the A4988 for my projects that use a stepper because I had them on hand but they can be noisy when running need to look into using the tmc2208 or 2209 so they would run quieter. I just built a wash station for my new to me/used resin printer maybe I should post the build on here for others. I used some atmega328p chips that I had and never used for the controller. I had to learn how to burn the bootloader to them so learned something new by using something I had on hand verses ordering a nano or mini.

    Great work on the various projects you have posted on the forum!!!!!

    Good idea. I took the easy way out and bought an Elegoo wash/cure station. I bought it and the Photon resin printer a year ago and still haven't used either :(. One excuse or another, need to do it soon.

    Thought my 3D filament printer was going south so bought another but it was just the screen module and a $30 new one fixed that. The second one has helped getting the coal mine project printed as there was a number of 10-12 hour prints so I used both printers. I still have a number of prints to go on the roundhouse also so like having the second printer will be helpful. Really like that I don't have to wash and cure with the Ender filament printers and for buildings feel they have plenty of detail. Would like to use the resin printer for small parts that have intricate detail.

    Get your wash station up, sure someone will appreciate that,

    I get that, totally. They seem so simple to use, 'plug it in, pour some resin in the vat, stick a USB stick in , and start printing.' But no, there are a thousand little things you need to do it safely and cleanly. Mine sat idle from delivery to first print for a bit more than a month while I built a cabinet and procured fans, heaters, trays, spatulas, cannisters, replacement FEPs, LCD protectors, ......

    Yes Glenn if someone wants to print without having to do to much a FDM printer is so much easier and cleaner to deal with. Won't do quite the detail a resin printer will do but I find it more than adequate for most N scale projects. There is still some maintenance that will have to be addressed from time to time but other than that pretty easy to use.

    Still similar to different welder types resin and FDM printers have their place depending on your needs and now cheap enough many can afford both.

    I am using my printers and K40 laser in the basement with ventilation going out thru a 6 inch blower. I have 3 anet A8 plus and now the anycubic photon mono. I have the wash station built and functioning, and have to build a cabinet for the curing station yet but its coming together. I like the A8`s for larger prints and will start using the resin printer for detail parts for the layout and rolling stock.
