Yes and no? The laser started working again and I'm not even sure why. But it stops working every now and then. I can only assume there is some issue with the board.

I'm using a 50W fiber laser engraving machine. It has a raycus laser and uses ezcad 2 as the controller. I've been going through the rounds and engraving/ cutting brass/ titanium/ steel for awhile...

Ah.... I think I've figured it out. I just created two separate configurations.

Hi folks,

First time user for solidcam here. I have a part that I need to program to cut on both sides. I am using a conventional chinese CNC router to do this. Is there a way to set two different...

Any suggestion would be greatly welcome before I do something stupid... LOL

So I purchased this machined a couple of months ago:
...

Hi Dreams,

Thank you for your reply. In the meantime I just saw some videos of some people crazy enough to try and actually achieved a semblance of success:
...

Well, it was just something I was thinking out loud with the following reasoning; If the router could indeed engrave (lets say 0.1-0.2mm depth cuts) then surely if I didn't really care how long it...

Oh my bad! Totally missed that, honestly thought you believed there was a chance and was trying to point me in the right direction, didn't realise that it was a way to cushion a blow. Thanks for the...

Hi R,

Thank you for the message. I checked the site and also did the same calculation here (as I'm a metric user): https://littlemachineshop.com/mobile/speeds_feeds.php

From what I can see, the...

So, under another thread I had an epic adventure of fixing up an old 3040 CNC engraving machine with an enclosure. It is an air cooled spindle with no coolant. Now I am thinking of all the projects I...

This is beyond frustrating....

So since the last time I posted here is what happened. Everything was working fine, the computer was controlling the spindle, switching it on/ off and speed. So i...

Ok..... a level of self imposed stupidity has just been realised. All is well now.

First and most importantly I would like to say a great big thank you to mactec54. Without your guidance, help, patience and knowledge sharing I am sure there will be many more burnt/ fried spindles/...

Hi guys.

I just started getting into CNC not too long ago. Struggled for the longest time to get the inverter set up correctly with the spindle but thanks to the great help of the forum I have...

Sorry for not being clear. The up/ down rpm problem only occurs when the spindle is controlled by mach3. Even if I change the delay settings, that will not explain why the frequency will not go below...

I reset to default again, and input the parameters again, however this time I input most of the frequency settings and monitored the changes. I then input the other additional parameters one at a...

Here are some observations I have:

1) If I set the knob to the lowest setting which is 120Hz, then switch on the spindle, it will spin up to 120Hz. If I then increase the frequency up towards...

Thank you again for the help. Here are the observations:

1) Setting P00=01 or 02 has not changed anything. The pot still is able to change the frequency display although the speed of the spindle...

So spent much time again today and FINALLY I am able to switch the spindle on with mach3. The frequency can be controlled with mach3 as well. However the speed of the spindle does not change with the...

Here is where it is at right now.

1) I have followed all the parameters correctly. I have triple checked this.
2) Running it from the inv panel allows me to control the frequency from 0-400Hz...

An update. I reset and input the values again. Now running it with the panel seems fine. Frequency can be controlled, from 0-400Hz. However changing the frequency does not slow/ speed up the spindle.

Furthermore, I assume these settings are not for a PWM control? Is PWM even possible here? Sorry for so many questions I'm just trying to understand more of it

Ok I will do that. Any idea where we went wrong?

Sorry it took so long for me to get back here, just been too busy and never managed to test it out. Today I finally got my act together, and followed your instructions and settings. After resetting...

I'm in Singapore, the main power supply voltage is 240V but the spindle/ inverters are 220V as they come from China. A couple of questions regarding the settings that you suggested:

P05=140. Isn't...

Awesome. Gonna give that a go.

Another question here. In my VFD manual, I can only see:

P03 motor rating (maximum frequency) which I believe I should set to 400Hz.
P26 Upper limit set of...

Ah, my mistake. I thought 'jogging' only refered to moving the gantry/ axis. I didn't even know the spindle could be jogged. Shows how little I know.

I thought the PWM was sent through one of the...

Thanks for getting back to me, I really appreciate it.

Why is jogging it a bad thing? I only really did it to test whether the axis were set up correctly. Didn't do much of it. Why did you state...

So, I've been struggling with this for the last 2 months. I have given my all, watched enough youtube videos to cry myself to sleep for 2 months and have read all the forum postings on Huangyang VFD,...
