Default Avid Nema 34 electronics connected to aftermarket VFD

Well I get a few bucks back from tax and seeing as already purchased Avids Nema34 steppers and cables , Iím tempted to buy their Nema34 completed electronics cabinet and be done with it .
Iím wondering if there will be any issues booking up an aftermarket VFD to their box , as I wanted to buy an 80mm Chinese spindle to save where I can . Avids spindle will be over 3K by the time itís on my doorstep.

Or I could use the money for insulation

I donít always insulate , but when I do .
Ok ,I never insulate

Insulation is overrated... unless you're in Canada or Louisiana!

Aren't these independent of each other? You get a signal from the electronics to start and control the VFD/spindle, but it's just a signal. Unless I'm missing something.

Iím not seeing what would be proprietary with their vfd and spindle . Iím thinking it should be compatible with a different model, but your the expert

I did email them for a price and asked about this . I havenít really had any luck with emails in the past though . Best I just phone them ,but Iíve got this perpetual cough right now and itís difficult to talk

This insulation issue started before my time and I'd say you have a better chance building
this machine now that you can use antifreeze. It's a shoo-in.

I have a Hitachi VFD connected to the Avid Control Box that controls an 80mm 2.2kW water cooled spindle. Works great! If I were building another machine, I would likely go with Avid's spindle and controls. However the VFD, cabinet and spindle cost less than $1K. If you go the none Avid route, save yourself a lot of problems and buy the cable that connects the control box to the vfd from Avid unless your an expert in soldering small electrical connections. Its not that expensive and you can cut it in half and have a spare cable.

Thank you . That’s exactly what they recommended

Hooking up an aftermarket spindle is possible, although we can only help with the interface to our control box. I'd recommend we sell you the spindle connection cable included in our own spindle package, which runs $49.75.
Not sure if this means there’s going to be issues with software ? It’s tempting to buy their spindle also , but wow is that a lot of money .
I do believe a while back that Ger21 said it was a quality spindle though

I believe Gerry also said you could buy several Chinese spindles and VFD's for you'd spend on one of the Avid spindles and VFD's.

But I didn't go back and see what he said, just going on memory.

No doubt the Avid equipment is good, though.

Ya the Avid one is $1700 ,which is double by the time it’s on my doorstep . So we’re taking $3300-$3400 for their spindle and vfd .
Amazons is $549 , (went up 50 bucks since the last time I seen it ) but considering the economy is done ,this will probably be mostly a hobby machine anyways ..

They wanted approx $2,000 for their cabinet , which will be close to or $4,000 when I get it .
For me to buy a large cabinet would be $500 Canadian, and the four steppers I need are $139 US each .
The stepper PS is $210 US , and then there’s the miscellaneous . Could probably save a few dollars building the electronics myself , but not too terribly much

Gerry was right when he said you could buy several cheap spindles for the price of Avids. But the Avid is one he** of a spindle. I'm on the second cheaper one on my Probotix ....... don't want to tell you what was ruined when the first one puked. I bought the whole Avid kit since my electronic abilities and knowledge is limited. Followed the directions and it worked. I'd rather cut than wire. Some people like to make jigs while others like to build things.

Now - if they'll just make a machine that paints, stains, and polys.

Rick - you could insulate while the machine was cutting.

I took the tests and retirement is the best job I'm suited for.
