reading marc's comments i thought he was asking for a virtual estop button which osha isn't going to like. No, not at all. I was suggesting that the appearance of the VCP reset button could change, depending on whether the actual emergency stop button was pressed. This would make it more obvious to...

The Z will perform well straight up on a 5mm pitch ball screw. Adding reduction is overkill

That said, you need more reduction on the x & y. Less than 1 is not recommended

the reset button is not an estop. Dont want it to be one. I have physical working estop switches the vcp reset button is resetting software, CNC12, clearing fault messages etc. You forgot that it also toggles the NoFault output when present a virtual 'estop' isn't an actual estop and can not be lab...

Testers.... This is in regard to the action and state of the onscreen RESET button. If memory serves me correctly, when an alarm or the ESTOP was triggered in earlier versions the VCP RESET button state was changed to RESET TRIPPED. This action does not occur with the current release v5.08. The foll...

Thats what I get for AVID 20t on motor 64t on pulley 20t spur gear:

For Guys that wish to use the C86ACCP interface board, here is a doc that simplifies the installation and allows you to test/bench test a single motor, etc.

Also does the PSU (MEANWELL RD-35B) that comes with acorn board have enough power for 5 NPN proximity switches?

thanks John.

Yes, and Yes

Update April 2024.... We are now offering a lesser cost modular version of the Acorn 4 C86ACCP controller for ClearPath servos. Featuring M12 connectors for inputs and a matching 14 pin connector for spindle control, including CNC Depot ATC spindles. Compatible with up to 2 Teknic power supplies, in...

This may help a bit...
1 rev per minute = 360°/min
1 rev per second (60 rpm) = 21,600°/min

Depending on your hardware neither one of the above are considered very fast. I routinely set my max rate at 144,000°/min for low reduction wood cutting, with fast jog at 7200 and slow jog at 720

2.5 to 1 is seldom enough reduction to return good results. That said, you need to know exactly what the reduction ratio is. Divide that number by 360 and you will have your turns per degree.

For example for 2.5 to 1 reduction: 2.5/360 = 0.006944
