That's really good advice, what type of chiller and temperature do you chill to for reference? As for the quote, out of context. [The reason why I would buy a fridge and why] I am not buying an...

As for cannibalizing a refrigerator, I will consider it, but not a clue how I could cram something like that in something the size of a K40 or glowforge laser, maybe I need to look in the mini fridge...
Hmm good ideas, well, this is a half hearted crack at the numbers and I'll use an 800mm(~40W) laser tube for example:
Working Voltage:15KV (Trigging Voltage=22KV)
Working Current:18-22mA...
Building or buying a laser is great and all but to get the maximum efficiency in power and longevity, the tube needs to be kept cool to room temperature and preferably a little below. Ice cubes in a...
What do you think are the chances the machine caught fire and burned down ttnc4plus?
fixtureman1 has the right idea to check the air assist, on a machine that large, would be surprised if there...
Doing an update on the modeling work and just wrapping up with most of the Y-axis when not working in infinite mode. Going to hold the laser tube right long the length of the machine just like a...
Fixtureman1:
Thanks for the tip, guess that's a vote for 80w :) I am thinking of using a quick swap focus lens and nozzle for air assist, the idea would be to use a 20mm (0.79") diameter and 38.1mm...
Minimum 1/4" plywood with varying densities and 3-5mm acrylics, if I can cut 1/2" plywood, all the more fun but not a requirement. I don't need something supersized but I want something deadly,...
Cool and yeah, hoping for the same thing. and neat way how the JC Vision Camera System works. Quite a bit food for thought haha.
And that is a good point, a USB hub would be much simpler. Thanks!
Good to know, guess I am pretty interested in a parallel mounted camera if it is pretty precise. From what I can gather I just tether the camera and cohesion control board to two of my computer's USB...
I just saw a video of light burn and what you can do with a camera and I am really impressed. I think some of my friends and family could have a lot of fun with a feature like this.
Interesting on...
Thanks, glad to hear!
I’ll model a few simple parts like tube holders and other mounts to give Onshape a try. It’s hard to say how I feel about everything I make being open to the public so I...
For Storen:
Scratch build haha, I did not realize I was implying I could have wanted to modify a Glowforge so lesson learned for the next title I make. Thanks for pointing that out :)
Yeah, this...
Thanks jfong! Alright, then Nema 17's it is for now, I'll keep a little space for upgrades down the road. Talking with you guys really opened my eyes to quite a few curious things I'd really like to...
Glad to know Zorbit, no worries if you don’t have a laser, same here haha.
Those are pretty thick screws, I normally work with 2mm pitch 8mm diameter lead screws in printers in the Z axis and only...
Awesome, great to know about the boards, I’m flattered you suggested the Ruida, I’ll keep it in mind for this project and recommend it my friends if their shopping too.
And wowzer, did not think...
Good points, I’ve never done an h-bot this big before, I think you’re right there would probably be an unhealthy amount of play. Cartesian it is, I certainly don’t mind a simpler build.
As for...
Thanks for the tip! I’m going to consider the 60w tube a lot more now.
I think you’re right it is impractical to buy and upgrade a glowforge. I’m a bit too poor and proud for a glowforge and their...
Hi, I've built a few large 3D printers and a CNC machine, now I am looking to round out my arsenal with a laser so I'm humoring myself with what a custom glowforge design would look like. There's a...
I suppose I should clarify I'm not looking for a new machine, the machine is already built, I am just looking for bits to use in it because this machine will also be expected to mill wood, soft...
Very cool, sounds like it should work, if cooling the glass is such an issue, adding a cheap 40mm fan or 50mm blower to add some air flow or even a fan blade to the tool bit could keep the plastic...
Thanks, gotta admit I thought the bit looked like it would be too delicate but the price really makes me curious to see what it can do. I did a quick search for some softer bits and some sintered...
Hey! Building the same thing right now! There isn't a lot accredited information out there on cnc machines for stones so it's a case of throwing oneself at the problem head on. I don't know if any of...
Interesting, those are really good disclaimers to know about. What are the toughest stones that you might cut through? Quartzites? My machine will be pretty similar to the stone pro's stone shark cnc...
Hi, new to stone fabrication but I got a budget to build a CNC machine to mill granite and as a non-required goal to also engrave simple reliefs on leftover pieces. The build of the frame and motion...

The spindle says 8.5A on it so I set PD142 to 8.5. At the moment I have it connected in parallel with every one of my power supply's live, neutral, and ground (60V to about ~14A) through some snap...
Well, I am a bit weirded out but it is working! There were two DCM and ACM ports so what I have wired up is VSO to VI, M3/M5 to FOR, and GND to DCM on the line of upper ports with the FOR and a...
Thanks! Looks like wiring up DCM, FOR, and VI and changing PD001 and PD002 to 1 instead of 2 did the trick for turning the spindle on and off! I did a little jig when it worked haha. I haven't tried...
New to these forums and CNC (Sorry if I posted this in the wrong spot) but would really appreciate it if anyone could give me some helpful advice on how to connect a DDCSV offline controller to a...
