Mach4 General Discussion / Re: Mach 4 and fc300 VFD

« Last post by joeaverage on September 11, 2025, 09:19:02 PM »

Hi,
good old-fashioned Chinglish!

Chinese VFD's are cheap, but thats about all they have going for them.

I use Delta VFDs (a Taiwanese brand made in China) for twenty years, both on my own equipment and for customers. Never had a failure and vastly better documentation
and set-up software.

General Mach Discussion / License not working

« Last post by Pugman1 on September 11, 2025, 04:42:41 PM »

Hi, due to new computer I had to download mach3 again. However when I downloaded the license which is registered to my account on the artsoft website I found that the license is not working. I have tried three times now with no joy. I have contacted mach3 support but no response yet. Has anyone else had this problem and what was the answer. Thanks

SmoothStepper USB / Mach 3 - C25XP/ESS to RSD110-6 drives

Hello,

Is anyone running this configuration?

Win11/Mach 3 - C25XP/ESS to RSD110-6 drives? 

I cannot get my motors to turn.  Attached is my wiring for an X axis test.  Anyone have experience with the RSD110-6 drives?

Its just I cant see any of the settings in the vfd, shows a 6 as it starts up then 0, dosnt display any changes when I run the cnc, nothing lights up like the run light or such,  I can go to each parameter but If I press enter on any parameter it dosnt go into it to change the value.

If you cannot access the VFD configuration, use an external 1.5VDC battery to simulate the analog voltage and jumper cables to close the contacts on the VFD and understand how it is configured. US or INTernational, then just set the jumpers accordingly.

I do not understand your comment regarding the resistor.

ok I found a small part in the Manuel that says it turns on both relay 1 and 2 for reverse direction in int mode, the vfd is not configured for that right now so if i have it connected to x1 and x2 m3 say will turn on relay 2 and m4 will turn on relay 1 and 2 but they both go the same direction, when both relay kick on i notice i cant use m5 to stop if, just keeps spinning, is there usually a pin that's supposed to be configured to the m5 macro? on the vfd there is a pin that stop can be connected to, but m5 works just fine when i only have one wire connected to the forward pin on the vfd. Apologies if my description is confusing, been trying to wrap my head around this for a week or so now.

Mach4 General Discussion / Re: Mach4 random crash

« Last post by RmaR on September 09, 2025, 09:27:04 AM »

Hi all,

It's been a while since I've wrote this post. Unfortunatelly I have not been able to solve this issue yet. It's still randomly crashing during the toolchange. So the M6 command has to go trough but then after that mach4 just closes. If somebody has any insights, please share them with me.

Thanks again!

ya looking through the setup of everything, it was all set to int mode, so will have to setup the pwn with a resistor from analog setup  I am assuming,  I disconnected everything from the vfd but cant change parameters, looked at external control and  password but I cant get passed the parameter number to change the value,

Appreciate the help, sometimes easier to start from scratch then figure out what someone else has done to a machine.
