you can get a pulse generator to manually control the CNC w/o a PC (search "CNC pulse" on ebay). Or if your motors are exposed you can attach a wheel at the other end and manually crank it to turn...

I run a Xylotex setup so wires are about 3.6v and 2.5 amps. I'll check out the AMP CPC, thanks!

I'm looking for a good (performance and aesthetics) quick connection plugs for my CNC. I was looking at Ethernet CAT5 cables but read they're not recommended for driving the current needed for...

I think the code starts with G20? Here's the 1st few lines:
"N1G00G17G40G49G80G90G94G98
N2G20T1M06
N3G90G00X4.62762Y2.55316S4583M03
N4G43Z0.575H0
N5G01Z0.45F7"

I use multiple profiles at the...

I'm building an experimental CNC so I created a new profile in Mach3 so I can use both old and new. The new one is faster (8 start Acme) so have it tuned that way in Mach 3. All is well, if I want...

I’m doing some research for my grad project and need some input. It's mainly about technology-based tools. Can you full out this survey for me (only 10 questions). Any feedback will be greatly...

Thanks for the feedback so far. I know about potential alignment problems during setup with portable/collapsible CNC, but I think I have a solution for it.

the4thseal, I'd love to see the machine...

I'm in 4th year industrial design and decided to make a new type of CNC machine as my grad project. I've already built a CNC so know the basics, but for now I'm focusing on the research part first...

I made a collapsible CNC since I don't have a permanent space to leave my CNC. Alignment is my main battle with this, takes a little bit of setup time that can me a hassle. My next machine will be...

I just came across this, anyone has any 1st hand experience with it or similar?

When I circles program my DIY CNC (Mach 3, open table/moving gantry), they turn out to be ellipse; longer towards the top-left and bottom-right sides of the circle. It still does this even when I...

I had the same issue with my semi-new built machine I'm still trying to figure out. The 1st time I was missing steps, my motors weren't tuned yet. I had to lower the speed of my machine to correct...

ebay will save you if you know what to look for. Search bearings and read a bunch of past threads to get an idea what to look for, etc. But in general you'll need (at least) 12 bearings and 6...

IMO a typical decent 1st DIY table would cost at least $1k for everything, give or take. You could get away with cheaper but may sacrifice on accuracy or something else. Most of the budget would go...

ya, using Mach3. Also haven't done much one fine tuning yet. I guess I should do that before doing any more test cuts. Is there a list of things newbies should check through Mach3, in case I miss...

I'm doing test cuts on my finished CNC, still learning how to use the CAM program (MasterCam X2), so am a total newbie to CNC. I programmed (through Rhino) to do two series of circular extrusion...

each bit does different things/cuts/effects, all depends on what you want to do

they may be able to cut it for you in the store, varies depending on the store and what in-store service tools they have

I'm having the same issues with my Univelop 5 axis board, spins only in 1 direction. The customer service is slow, the last email he replied back was 2 weeks ago. And it's been 2.5 months since I...

Xylotex to me was good quality, returned emails promptly, etc. Bought the complete kit, seems professional quality, it eventually had issues (probably my fault) so emailed them asking for help and...

for a 1st build I'd use cheap MDF first. Once you have things figured out then you'll have a better idea on what material and overall redesign to use on your 2nd build. Somewhat common for people...

just curious, what type of typical projects do full-timers get from clients?

Tried that before, doesn't work. Read the manual, got in touch with manufacturer, wirings and pin settings seems to be fine. Motor doesn't spin when pin settings are switched.

Also just got a...

I just ran some voltage tests. Parallel cables gets 3.5v/0v when switching directions. From the control board (testing output solder points going to the breakout board) I get 5v/0v. From the...

I'm trying to figure out why my board only spins in one direction, making sure if I missed anything on the software (Mach3). Right now when I jog the motor only spins in 1 direction; jog left and...

slow progress but progress nonetheless. Here's most of the Y axis finished. Will be doing the X axis soon and how the X + Y will be attached.

My plan will be to have the Y + Z parts (pictured)...

I was planning on running a fan on the heatsinks since I noticed the heat problem. Besides that, was there any issues other issues you encountered?

On a semi-off topic, how can you run more...

I'm working with the developer of the board with this issue, but thought I'd ask here too. I'm still having issues with the motor only turning in 1 direction: jogging left goes left, right goes...

It's sealed right now. Also just glued but about to put screws on specific locations. I'm just about done designing the Y axis so I can finally continue the build, so more progress coming soon.
