High loadable turntable

Hi Jeff,

Good to see your progress. And yes, the code is fine for a 1/2 step mode of the driver board.
I see you have used a fine pressed chipboard (MDF?) for the table's platter. It's so perfectly circular that you must have used a lathe or something similar.
I remember when I had sawn the 5mm aluminium plate with a jigsaw, after each 15 minutes I had to brake the work for minimum 15 minutes to relax my right arm muscles. Unfortunately my lathe can only handle diameters up to 250 mm. But this is better than nothing.

Have fun (and success) for the rest of the work.

I have a small CNC mill, with a limited Y of 150 mm.

I had to do it in two runs but it came out nice.

Yes, for the moment, both platters are in MDF.

I tested 1/8 step. I liked the smoothness. I will modify the software to adjust the rotation.

The funny thing is that the motor in "stand still" makes a noise after the two first rotation and then stops after the third. This repeats in each cycle of three rotations. But it's not important.
