I'm having trouble finding the 6600 on digikey. They're like $8 on ebay. So I looked around and found a 16 pin DIP chip that does 4.5A...
I still haven't decided on a chip but I do recognize the enormous price and power savings these ICs give. My first build was an h-bridge with...
So getting back to the thread, I may be making my own motor controller board based around the TB6560 using the parallel port and linuxcnc. If I...
Dude, windows is dead. Accept it. Maybe get some grief counselling. o_O. Maybe one day they'll have retro XP devices like those Atari emulators....
Also XP is end-of-life in a few weeks. No more updates from Microsoft.
Well I was kinda thinking of manufacturing my own PCB with my routy and add it to the builds as a 4-axis controller board. We'll see, still...
I have a dual-boot with winXP/mach3 and Ubuntu/Linuxcnc. I used windows/mach3 one time to test my parallel port and then never again. One major...
Well I don't use Mach3 but in Linuxcnc there's a tool table where you set the tool length. I don't have any builds worth mentioning.
My motors stall at anything faster than 1500. It all depends on your controller board+motors. I don't have plastic on my acrylic but it doesn't...
Look what I found: http://www.ecomorder.com/techref/ecomprice.asp?p=416074 I'd like to try to make my own board based off this design. It looks...
Haha, yeah with wood try 800mm/min and cut depth of 1mm. Acrylic is "special" like aluminum, brass, etc. You could try 0.5mm for really clean...
This is the same for all machines. Some people have a conductive plate that the machine touches with the tool-tip and then automatically calculate...
It's working with 200mm/min, 20% plunge rate, 0.0762mm cut depth. This is 1/2" plexiglass, so it's probably the "plastic with glass" type listed...
Well I'm all for freedom of choice and if that's what you like then by all means... When you save to a format that is incompatible with any other...
Thanks, that's what I need. I had seen the Jacobs chucks and was thinking I'd have to go to a machine shop and have a bolt lathed.
Yes but I need a round shaft 1/4" diameter
Does anyone know where to get a drill chuck with a straight shank suitable for mounting in an ER16 collet? I think I can hold a 1/4" shaft, but I...
Funny, my feedrate is set to 500mm/min(20ipm) and my cut depth is 1mm(0.04in). They suggest 0.003"(0.0762mm). I think my leadscrew pitch is wrong...
Acrylic is harder than wood. I use a 2 flute solid carbide 1/4" bit. At first I cut some foam but it sucked. Then I did wood and it looked great....
You can enable microstepping to smooth out the motion. You sacrifice holding torque though. The acceleration is totally programmable on the...
