So the 2.2kW Chinese spindles need a 3kW VFD?

So I've come across the Reyann brand of VFD on Aliexpress, on the face of it they look good and have great reviews. I'm just curious if anyone on here has any experience with these?

There isn't a...

I'm having difficulty finding quality shielded cables that won't break the bank. I'm looking for cable suitable for nema 23 steppers so 18awg/0.75mm^2

What have you guys had success with?

Cheers

Any update on this? I'm curious about what laser you're intending to use, got any links?

Cheers,

DST are their new motors and should be the best choice.

Why are your current servos not very accurate? DMM use 16384 CPR on their older motors and 65536 CPR on their new DST I believe, however 4x...

LET'S DO THIS!

90% fun changes everything! Haha

Maybe bringing new life to a worn out machine could be a good venture? All the fun of making a 'custom' CNC without having castings made and machined... There have...

Got any pictures of the Toyota? Post them up! :cheers:

Are the firearm parts for personal use or do you intend to make money from them? I believe that's a very competitive market, especially AR...

If I was to go the Tormach route I'd go R8/TTS over BT30 for many reasons. The price of the Tormach spindles / Head assemblies seem attractive but you have to think of what the quality is like, it's...

gt40 are you sure that base and column are big enough? 482mm x 940mm x 203mm at 2,500kgm^-3 is only 230kg (507lb). I think you changed the Y travel to 15"??? This is better than the original 20" of Y...

Great work! Keep the updates coming!

Well_Armed you say this is for hobby but 13hp is a lot of hobby you'll have there! At 10-20k budget you'd really be best buying a used VMC. A typical VMC spindle (say 8k rpm) has the ability to cut...

Nice idea you have there petruscad. I think you're crazy though for not wanting to go with solid base, column, and head! Do the cavities really save much money? Increased rigidity, damping,...

Looks like it'll be a vast improvement over any bench top mill spindle, 10,000 rpm and 13hp yes please.

Does it have ports for air hoses? Labyrinth Seal?

Did you manage to get any more tooling...

Are you intending to make money out of this venture? $5,000 may need to be revised if you are, even a Tormach 770 is $7,000 for the base machine.

You may be disappointed in the performance of a...

Hi pippin 88, that spindle you linked was from Alibaba, I'd steer well clear of unrated sellers on Alibaba. It is very easy to be scammed on Alibaba and $1,000 isn't exactly pocket change. I'm sure...

Hey
Not too sure what kind of mini mill it is that you bought but filling the castings with epoxy granite has been done on this type of machine to improve rigidity. Sure the rigidity of the actual...

Sounds good :) what kind of stuff are you going to be making? And for hobby or profit if you don't mind me asking?

You may want to keep the computer near the mill though for setting up stuff

My knowledge of USB isn't great but I've heard USB suffers from interference problems, whereas Ethernet doesn't hence why Ethernet has been the world standard for so long, it just works.

USB may...

Hi Eremius, what kind of machine are you planning?

Mach3 (if that's what you intend to use) can send movement signals to the stepper drivers directly through the parallel port. However given the...

Any updates? We want to see that beast moving :cheers:

Hey Loky, I don't quite understand what you said but from what you have listed the Tormach is what I would have. However remember that the Tormach is considered small, light, and slow when compared...

Love the build! I'm rather jealous :cheers: Any specs for the motors you bought?

That CS-LAB CSIMO-IPA Controller looks great, and judging by their site pretty cheap too :) I'm planning a big...

Again looking brilliant mate, bet you're really pleased :cheers:

Are you going to get the Tormach Superfly Cutter? I've only ever heard great things about that little tool, the finish should be...

Looks like you've done a great job there mate, can't wait to see it when it's all 100% finished. Bet it'll be a great little machine and at like a 6th of the price of a complete PCNC770!

I know this isn't ideal and I'm sure you've ruled it out already but what about a cast iron plate to sandwich between the head and the Z plate, then offset the head vertically.

I think it'll be...

Someone's been busy :cheers: just out of curiosity what brand is your granite square and where did you get it from?

Defiantly want to take a look at DMM. Their 400W motors will be ideal for your machine, directly driven to your 5mm screws should give you around 3 times faster acceleration at only the rated torque,...

Interesting build, I'll be watching this closely.

Shame to see the quality of the casting in that state, one would expect better from Tormach.

I'd defiantly remove the paint from where the...
