Hmmm, what about a used CPAP machine? It’s an air blower used to keep your airway open while you sleep.

It’s designed to mount up some decent pressure, pretty quiet and can certainly blow as hard...

Maybe this is worth looking in to? https://www.amazon.com/gp/aw/d/B06Y3QKQY4/ref=mp_s_a_1_13?ie=UTF8&qid=1510636715&sr=8-13&pi=AC_SX236_SY340_QL65&keywords=hvlp+paint+sprayer

I went ahead and bought it... it says it renews at $25 a year to, so I think it's locked in at that price. I thought there was tech support included with the license (at least via email.) and none...

It's web based, so I wouldn't think there would be a technical problem with it. Legal wise I wouldn't know though.

Has anyone gotten the email about F360 for $25 as an Amazon Prime deal? What do I get over a freebie license for that, does anyone know?

Or maybe a pass with a torch?

I would be interested in the vendor info too.

Also possibly of note... I ran in to an interesting belt drive conversion on YouTube in which it looks like they replaced the drive barrel with a different one custom made for the job...

Might a carrier block be an option, bolted in place on top of the casting using the factory threaded holes? It would have some adjustability that way. (If I am even envisioning the correct setup,...

$500 contact bearings definitely changes the formula for cost/protection ratio, LOL. I'm going to run it with a decent quality synthetic wheel bearing grease, worst case is I chunk a $30 set of...

I did finally find the "Ye old bearing grease, just don't pack it in like a wheel bearing" recommendation in a search. It makes sense... spending $40 to protect $30 in bearings didn't add up. If...

I am anticipating some time in the shop, and part of that will (probably) be spent upgrading the bearings on the G0704. What are some alternatives to the Kluber? That stuff is more $ than the...

Do you have the enable pin set "High" or jumpered over to a 5V signal? (Look at the "Master enable switch" on the upper right of your diagram. Just a first thought.

Wow, what an awesome thread, LOL. I have been eyeballing the K40 laser and reading up on it... the price is sure appealing. I am familiar with Arduino so this sounds right up my alley and cost-wise...

There are some less expensive driver options. I used the electronics kit from Massmind.org and have been quite pleased. I haven't had any real problems with it once it was setup and tested. It...

It's doable but you have to trade work/research for dollars. I did a G0704 for around that. I used a kit for motor mounts that put it a little over that. Make your own and the materials cost would be...

I have mine set up with joypad control. I use it all the time for "manual-ish" machining. I can set my feed speed to the correct setting, then just "drive the mill around" when I want to do...

Stepper voltages are...... Weird. I'm not sure in what applications they are actually used as rated but it is standard practice in CNC applications to run them at multiples of rated voltages. I'm...

I'm using a 282 oz stepper on x/y on a a G0704. I test successfully at 180 IPM and run it at 150 ish with no issues. As long as it's reasonabley matched to the stepper driver I think it will be just...

I think I had that problem too. If I remember correctly I just rounded the corners on the ball nut flange on my bench grinder.

I'll 3rd or 4th the recommendation for Arizona's kit. Everything was well made, well designed and well finished. It is all working great

First, there's nothing magic about "Hand scraping".... especially as it relates to this imported mill. I'm glad I tried it and it is a super useful thing to learn, but not really (IMHO) needed to fit...

I use that same board. I don't think it has any kind of spindle output, or if it does I wasn't able to figure out how to use it. There's a couple of options.... for cheap and dirty spindle control...

You sure you didn't mix up gibs? There's two that are close (but not quite the same) in size, had me scratching my head till I figured out I had swapped them.

I actually have been getting along with (2) 262oz on x/y and a 570 on Z with a 4A/42v driver. It will do 180 ipm but I have it detuned to 120.

Not sure I have a point except as long as your choice...

I'm grossly ballparking here, but I get about $1500 as my budget for conversion...

Power Supply $45
Drivers $100
Breakout $20
Steppers $180
PC Free
LinuxCNC Free
Ballscrew/Mounts kit $650...

I definitely love open source stuff. I wasn't particularly aware of Grizzlys kit. I had looked at some other options (all in one kits, packages, cheapie eBay stuff) and mostly the 6064 looked like it...

2 Years in the making, LOL

I tested at 180 IPM without issue (150 on Z) and I'm running it at 150 X/Y and 90 on Z. Is that enough headroom or should I maybe drop back a little more?

...

Heh, nothing like life to slow you down huh?

So, almost 2 years later LOL.....

That's using 3 of the Massmind stepper kits running a G0704, I...

I get the why, lol. Just to see you can (and learn something) is to me the very best of reasons, lol.

Cool project, I'm tracking along just so maybe I can learn some myself. I'm familiar with...
