Re: stepper online servo

These are Leadshine Servos, driver is without 0-10V input.

They work fine with Acorn, 200khz on Headers and up to 500 khz on DB25.

Easy to wire, because all screw terminals no soldering for a custom cable.

Re: JMC 220V Servos with Acorn

Glad that it runs now smooth.

Resonance is maybe from the belt, try to get a bit more tension.

Re: Need travel consistency but its not working as expected

0.012359x1618 Steps=19.997

One step more would be 20.009

There is no way to drive to 20.000 and CNC12 is going as close as your setup allows

Use gear reduction or setup to a higher resolution.

Re: Need travel consistency but its not working as expected

You have set up 9.8872mm / 800 steps = 0.012359 mm / step So no way to hope the axis will drive with 0.001mm accuracy The smallest increment the CNC can control with your setup is 0.012359mm Related reading: https://centroidcncforum.com/viewtopic.php?f=63&t=1801&p=11936&hilit=happy+zone#...

Re: Solidworks for $38.50 a year

Alibre is a German product, and they are also cooking only with water... Expert version one time 1904 € + Service/Updates 690,20€ / year IMHO fusion is a better deal for 490€ / year (the price I payed for the abo next 3 years) more modelling features and 3+2 axis CAM included I like the streamlined ...

Re: CNC12 V5.09 beta REV3 is now available for testing.

Reset Logic was always different in Acorn than in Acorn6.

But since I cycle reset after start up, I did not mind it.
