Dang thats what I thought, well ill have to convert it to stepper control :)

Thanks!

Also can you recommend a good thc?

Hello everyone! ??? ??? ???

I just picked up a cnc plasma cutter that needs a new control, but I have one question about the THC. I am very familiar with wiring and can easily wire the rest of the machine.

The Torch Height Contol has a 24vdc motor for moving the z axis up and down, it is not a stepper motor. Can I use this with mach 3 for the THC? I am not sure how to set up the configurations either.

Any help would be greatly appreciated!

My thoughts pretty spot on! :)

I would like to first try the VB, then if that doesnt work then just get a servo, the issue is that I love retrofitting machines, and always buying and putting servos on the tool changers are not always possible without heavy modification.

What size servo do you think I would need to move the umbrella? I was thinkinkg like a 200 watt motor? the current motor is a single phase motor with a gear reduction,

Thank u ;), any idea where I can get a good servo and drive that talKS +-10 volts for input? I

Could I just use 24 inputs? One input per tool position, then just run the tool changer till it hits the right input, the initiate tool change?

Scratch that only got 24 inputs :(

Hi! Sure I can take some more video tonight, I think the operation of the tool changer is. Z to tool chage position(switch to indicate tool change position) then run swing arm motor till a switch is triggered, then stop tool changer motor arm, then activate tool changer fingers extension, then activate air cylinder that lowers arm (pulls out tool) then activate tool changer arm motor (moves to tool changer carousel) then de activate arm lowering cylinder (pulls tool into carousel) then deactivate fingers (restracts) then spin carousel to new tool, then reverse the previous steps.

I do also think it would be a lot easier to mount a stepper motor on the bottom with a home switch (one of the pre existing switches at the top! Lol), but the problem is that I have a csmio A driver for analog +-10 volt drives, which means I have to buy amother drive and motor :( just for the tool changer, I have a ton of steppers laying around, maybe a gecko drive and keling servo would work...?

  ;D

Hello, I am retrofitting a cnc knee mill with a tool changer that has some kind of switched logic, can anyone help me figure it out?

It is basically like a rotary encoder with logic from the switched that indicate tool position, there are 24 tools...

here is a small video I made https://www.youtube.com/watch?v=OsBAYHpI6es

thanks for any help!
