Does MACH4 not thread with a 1PPR sensor? John Sent: January-31-21 11:03 AM To: [email protected] Subject: Re: [MachCNC] Lathe Threading I have succefully used mach4 several times to encoder cut

Hello Graham,I have attached a pdf of all the macros I use with Mach 3. There is quite a variety however on page 3, M911 and M910 turn on and off the first of 8 outputs I use to control solenoid

I have a couple of things that recently happened with my Mach 3 setup.? It will no longer rapid when pressing the shift key on the keyboard.? It used to work but I must have accidently changed

I haven’t tried in in real control, at least that I remember, I tested it and watched the diao screen output leds for the outputs4 and 5 they did go on and off in mach3’s screen so I assumed they

I have succefully used mach4 several times to encoder cut various thread on my lathe. It works fine. Here is a video (43) Encoder threading with Mach4Lathe and the pokey57cnc - YouTube (

The problem may be with the plugin for your board.

Hi Gary Thanks for your ideas. I had opportunity to day to spend time. Using O/Ps 3,4,5 & 6. Allocating these to M3 all switch using M3/M5.? so it can all work I tried the ?turn on using

Does the vacuum pump have to actually be hooked up and running for spindle to start? I have tried toggling vacuum button on mach3.? It lights up and I hear a relay but I haven't ran power for the

Yes,? here's where I'm at.? I fixed the reversed tool clamping issue with the information provided by others here.? Thank you. I just manually turned on the spindle and tried to control rpms or

If I understand you correctly, in the diagnostic screen you can toggle the spindle button and presumably you will see the LED output diagnostic also toggle and you hear a relay switching. That sounds

Thank you for the replies. How do I tell how the spindle is controlled?? What should I look for?? ? The VFD says "0.0 "on the display. I tried toggling spindle on off thru diagnostics and mdi

just a wild guess, but you say the auto tool holder is reversed, is it possible there is an internal interlock that disables the spindle motor while it thinks the tool clamp is open? Chuck S.

If you want to just get started, I would recommend reversing the hi/lo as Andy recommended, and consider toggling the spindle manually. I know it isn't ideal, but a lot of good parts have been made

Sounds like you need to reverse the “Active Hi/Active Lo” setting for the Auto tool spindle release. That should stop it from acting backwards. How is the VFD supposed to be controlled by

Hi, I bought a used cnc and can't get the spindle to turn on.? It's a Boss cnc router 10hp spindle.? It has mach3 installed on it but no other info.? I've watched a lot of tutorials and changed

not sure if this will work the way you want, but you can turn on and off outputs with something like this DoOEMButton(233) 'output4 on DoOEMButton(234) 'output4 off DoOEMButton(235) 'output5

Graham: ?Most likely would be another output set to the same pin. Cant think of anything else that may do it.. Art -- Thanks Art www.gearotic.com

I wish to control via relays, Using Mach3, VB and MK4-ET V1.5 XHC Motion card., Omron 24VDC relays. The "ON" code is M704, and content is ActivateSignal(Output4) : This works The "OFF" code is M724

Have you tried this; https://www.grblgru.com/ Can't say I've got it to work yet, but you might have more luck...

Hi All In Mach3 Turn; When one clicks on the button "Set Home X", the axis moves onto the switch, and backs off, setting the reference point. However, a G28 or G53 simply moves... to that position.
