My shop has a 1994 VF3. I was reading in the book that during drip feed there is no look ahead. Maybe I misread that... does that seem right to you? I ask because I am looking into 3rd party...

I didn't look closely at your rendering, but it looked like just flat surfaces, maybe some edges for the rails, drill and tap some holes. If that's the case, a boring mill is the way to go. And a...

Oakland Machine (Pontiac). Hallmark Tool (Wixom). The other Three M (Wixom) has (4) huge G&L floor mills.

A boring mill is *designed* to do work like this. Ask me how I know (I grew up running them). That machine you've linkied to has 60" of Y. Plus whatever table it has. There are tons of these old...

Maybe it's a hundred bucks. An 80" devlieg is at least 40 years old, and costs very little. But one in decent shape will hold those flatness and parallels better than 0.0005". The point is that it's...

Easy peasy. Find a boring mill shop. One with an 80" devlieg. I don't know where you are, but there probably a dozen around me within 10 miles. Often $75/hour shop rate. Machining those rails and the...

It never occurred to me to check, but it turns out you can turn the WBK12 (some call it FK12) bearing around, and in this case I could do that by putting the bearing inside the gantry to reduce the...

Guys,

I have a mockup of a CNC router I am thinking about. I wanted to tuck the gantry motor behind the gantry, and run a belt between the motor and the ballscrew (1605). Take a look at the pics....

Totally clear. Thank you.

Thanks for the help guys, this thing is cool (got it yesterday).

I'm new to DIY CNC boards and home wiring. What sort of power supply(ies) would you run? The AXBB asks for 24V & 5V. Is that...

Looks like mine will be delivered today or tomorrow. I bought it because it checks a lot of boxes on my list, but I'm surprised how scant the information exists about this, at least on the cncdrive...

This is what I had in mind when I asked. Many computers these days are showing up w/o the RJ45 jack.

Excellent, thank you!

I understand the arguments for ethernet connections over USB for signal fidelity, speed and the rest. But ethernet presents some inconvenience as well. I'm curious: would it work to use a USB-to...

dharmic, thanks for the info. It appears I have some learning and wiring to do! LOL.

Thanks for the heads up, I just sprang for that. Good selling to me guys... you managed to get me to rethink certain areas where I have specifically leaned toward convenience: preferring USB over...

I am WAY WAY late to this conversation, and I haven't read everything that was posted, but I wanted to address this. This is in reference to a sketch Handlewanker submitted with "A" and "B" z-axis...

Great ideas guys. I need to weigh these things. I'll be honest, I'm highly motivated to keep the electrical side of things simpler. I don't know why, but I am simultaneously unafraid of the clearpath...

Thanks or the advice. I will gladly research those. Some (not all) of the attraction to clearpath is, of course, the SD line that drop right into step/direction controller boards. The ubiquity of...

Thank you for the help. Yes, it appears that perhaps what I am looking for doesn't exist. I found this...

Hmmmm….

Thanks everyone. Let me ask this again, and hopefully make my goal more clear: I want a breakout board with built in stepper drivers that's *cheap* because I am essentially going to waste...

I've been building a CNC router, and I think I want to settle on UCCNC. I've been playing with the software and it ticks a lot of the boxes on my list (except cutter comp... grrr!). Anyway, I like...

yes

Great info, thank you! A little off topic, but given your professional experience, is there a quick way to reduce backlash on the VF3's table? I can put an indicator on the t-slot, and with my hand,...

Thanks all for the help. This machine def. has the lube tank, so it must also be for the spindle. Appreciated.

I appreciate the note. I should look again... I noticed the lube tank, which I believe is way lube, but I didn't notice a spindle oil tank, but maybe there is one and I didn't look hard enough. I...

Pretty cool. You're kind of making me think of something. As a related tangent, I sell Okuma CNC machines for a living https://www.okuma.com/americas. To my knowledge, Okuma is the only [commercial]...

Sounds like it allows MS visual basic.

Can you give me an example of some of the uniquely powerful things about mach3? I noticed the Masso has "wizards" that look like rudimentary conversational programming, which I thought was cool.

The fanuc sub program method is EIA standard for commercial cnc for the last 40 years. But while the subprogram is a unique "file," like O2020 in your example, you have always been able to embed them...
