Hi, thanks for your interest. My friend's wife doesn't want any payment for the machine, but if any new owner felt it warranted some payment, a...

The click is from the VFD, not the contactor which kind of 'clanks' straight away on power up, there's is an audible soft click inside the VFD 2-3...

Just watched a few YouTube videos and have just got everything to bits. Yep its a standard bearing and one is very rough. Ill get a replacement...

Looks fairly simple - remove the screws holding the bearing block to the frame, then pull the bearing block off the end of the ball screw shaft. It...

If your controller is using GRBL, then there are settings in GRBL to reverse the directions of travel - its simply a question of typing a value...

Mark, I'm very interested in your CNC. I lost my entire workshop in a fire last month - all uninsured - and am gradually starting to think about...

I guess the question everyone will be asking, is how much is your friends wife looking for, for it ?

I don't quite understand why the contactor coil would burn out, as that should be totally independent of anything that the VFD is doing. It does...

I've installed quite a few of these Huanyang VFDs on different machines in my workshop and all have worked for years except one a long time ago which...

Hi Farzad, I'm not aware that anyone on the forum has used the Vibration Stress Relief process, but I could be wrong. There is an abstract to an...

The MCB didnt smoke, it was the contactor- A1-A2 coil. The tricky thing is sometimes the VFD will start fine, to the point it will communicate with...

The MCB should never emit smoke or suffer a burnt out coil, no matter what load you present it. That suggests you either had a duff MCB or it was...

m_c; Drives using 24v for motors and 5v for opto-couplers

Hello again m_c; All motors and drives now tested and working OK. I'm hoping not to spend much as it is for hobby use and I couldn't justify...

Hello NikosR. I have already put photos of my machine on the 'Introduction / Welcome sub-forum a week or so ago. I'm attaching some photos of the...

Upload some photos so we can see the machine.

Quick update - I purchased a few brass wheels for the cordless drill today and so far, it seems to be going well on the cleanup. Going back to my...

Thanks for the replies chaps. The rust is not too bad at one end but is quite bad at the other. I think the unit was a bit tilted in storage and...

Hey Stephen depending if the rust is particularly nasty or not.I have used “The Pink Stuff” on my lathe that had surface rust on it and came up...

Use a rust eater that doesn't contain acid ie a chelating agent. The market leader would be Evaporust...

Looking good and very strong. Keep the pics coming.

I was just browsing around, and (very belatedly) came across this thread. I had much the same problem some time ago, and while I agree that...

Only thing to be aware of if using the original drivers, is what signal voltage they need. That age, they might use 12 or 24VDC logic, not 5VDC.

Welcome to the wonderful world of CNC. My opinion is that mac3 is very good for beginners and relatively easy for the basics. Good luck in your...

Hello m_c, Thanks for the input. The machine owes me £200 already (£159 to buy it and around £40 in fuel to collect it) so I am thinking of taking...

I'd guess those stepper drivers date from the 90s, so there's every chance nobody remaining at Infotek who actually know anything about that age of...
