Closed loop stepper motors

Post by Grahamd666 » Sun 23 Apr , 2023 17:23 pm

I’ve got a Novamill which I’m looking to upgrade. Looking through some of the threads people have used bigger stepper motors but I was wondering if anyone has ever fitted closed loop stepper motors.
I’ve also purchased a touch screen all in one computer and I’m looking to connect via an Ethernet connection.
Thanks. Graham

I have just converted a Novamill to Centroid Acorn control and a Gecko G540 stepper driver. I am still using the original stepper motors and they appear to be working well. The Acorn board is a Ethernet connection to the touch screen computer. I was able to reuse the existing wiring between the mill and cabinet as well.
I plan to use it a while and maybe upgrade to Teknic Clearpath servos eventually if it earns its keep. The Clearpath servos should interface well with the Acorn board. The Y axis motor might be a challenge as it has to be pretty short for clearance. I might have to put in a column raising block at the same time or reorientate the motor out the back to make it work.

Hope this helps

Ben
