Hey Graham thanks for the reply. Yeah I am using g61/g64 I guess I just noted wrong code in my post.

Mach4 General Discussion / No response to any CV settings in mach4

« on: March 09, 2020, 09:55:18 PM »

Just in the process of upgrading to Mach4 from mach3 and everything is working great except for Constant Velocity..

I am calling the g56 enable code and motion mode is set to constant velocity in mach's settings. I am using the same known good gcode that works great on mach3 with CV.

I have tried using the wizards to configure the CV settings and also manually adjusting it in the machine.ini file. No matter what direction I go with the settings I get no response. Machine keeps running in exact stop mode.

My machine uses an ESS with build 253 plugin and Mach4 4322.

Hopefully its a simple fix. Happy to pay for someones time to solve the problem for me!

Thanks.

General Mach Discussion / Re: MACH3 THC not responding to torch up/down inputs

Thanks alot for all the information! I always just assumed the thc function was script based like your describing mach4 to use. I keep forgetting this software is almost the same age as me and designed around much slower systems.

I have downloaded mach4 and looks like I wont be able to make this nvem v2 work with it so I will be upgrading to something better. Maybe use this nvem for some other future project.

It sounds like the Ethernet SmoothStepper would be the best option for me. Looks like they support mach4 too which would be a nice upgrade.

I will keep messing with it while I wait for new controller and update this thread if I find another solution.

Hi,

I am using the nvem v2 controller

I wasn't aware that your controller supported THC.....do you have documented evidence that is does so?

Craig

I have no documented evidence that my controller supports THC. This is my first cnc machine so I was not aware the controller itself would need to support that. I assumed it would be no issue for the software to simply take a torch up signal and move the z axis just the same as if i was jogging it manually by hand.

I tried setting torch up/down signals to z jogging input but it wont move while running g code. is there a bypass setting that allows me to jog z axis while running a program. I would imagine some guys run with no thc and simply adjust manually while cutting?

A step at a time
1. Is your plug-in "Novusun_NVEM-Novusun-PlugIn-Ver-3.0b" or later?

Yes Plugin ver-3.0b is installed and working correctly. Have also tried reinstalling software and the plugin with no change in results.

General Mach Discussion / MACH3 THC not responding to torch up/down inputs

« on: March 26, 2019, 01:19:25 AM »

I have built a 4ftx8ft plasma table from scratch and everything so far has been working great except the torch height controller function in mach3. All ports/pins are setup correctly and diagnostics screen shows arc okay, torch up and torch down signals working correctly.

I am using the nvem v2 controller and pricecnc thc connected to my hypertherm 1250. Voltage readings are correct and its sending torch up/down/arc okay signals no problem while running some cuts. The Z axis just simply is not moving from torch up/down signals. I have tried emulating signals with keyboard as a test and still no movement. Page up/down jogging z axis works fine and my g code probes the work surface at start of every cut no issues. The arc okay signal does work. with plasma cutter tuned off G code will wait for arc okay before proceeding.

I have tried enable/disable "allow THC UP/DOWN Control even if not in THC Mode" and it makes no changes. If i enable "set OUTPUT5 when in THC" output 5 does toggle on when i switch on the THC enable button. Running in mm and THC max = 20mm minimum = -2mm. THC Speed = 20.

I'm sure its something simple I have missed but don't have much experience with this software yet. Would greatly appreciate any help you may be able to offer. You can see a video of my setup here: https://www.youtube.com/watch?v=RcUxoCZ0VbE
