HI John, thanks. I'll head on down to the local S&A tomorrow.
I want to add a cooling fan(s) to my gecko 201's but I just realized I have no idea how or where to connect them.
What voltage do they take?
I have campbells BOB if that matters.
Thanks, John
Thank you for that reply.
I haven't checked any jumpers inside the geckos, but as for your other questions, yes the limit resistors are the same, motors are same models and wired the same (they are...
My home brew router has gecko 201's.
One of them feels noticeably hotter than the others.
(I already read in the FAQ's that if it's uncomfortable for me, it's uncomfortable for the electronics...
Chester, thank you, thank you, thank you!
A concise, plain english answer to all my questions.
OK, I'm reading all this about the current set resistor, I'm still confused but I' probably not the only one.
My motors are 5.5 amps/phase
gecko says use 120 k resistor for a 5 amp motor and 270k...
I am looking at this gecko 540 4 axis system.
Do I make my own cables to connect to the DB9 connectors?
Also, I can't picture in my head how the current set resistors hook in.
Thanks, JOhn
Thanks Richards for your reply.
Is there anything I can do short of getting a new transformer?
There is a good tutorial on building power supplies here:

If the link doesn't work go to campbelldesigns.com and follow the links to...
I bought motors, power supply components and geckos, not as a kit, but supposedly "matched", if you will, for compatability.
I am wondering if my DC voltage is too high for the motors... they seem...
Yep, you can. There is even a tutorial in the program to show you how.
One thing I didn't catch on to right away was how to open different drawings on the same screen. Quite simple though... under...
Is there any way,easy or otherwise, to restart a plasma job mid stream?
Say after computer crash or tripped circuit breaker....whatever???
Hey, a question maybe I can answer!!!
I had the same issue.
click on the "layers" tab, then enter your desired height.
at least I think thats how i did it.
In the end I still use sheetcam:)
Thanks guys,
I will try to mess with it today (being Sunday, my wife may make me watch football all day :)
you all certainly gave me some good ideas to try.
I think I will :
shorten the z...
I'm not sure if it's cv or exact stop (I'm not at that computer right now)
I'll check.
Which should it be?
Also, I'll work on getting a couple pics.
John
Thanks, dsl_
I didnt think to run a program with the motors out of the rack. I'll try that.
I have 2 stepper motors on my long axis, 1 stepper on short axis.
Gecko 201's, microstepping.
I may...
Please help me determine if my plasma table is jerky because of the mechanical design or motor tuning.
The problem is when making rapid small movements the torch holder shakes too much....
Chevy,
If you are looking to buy motors from homeshopcnc, ask Rick if he still sells power supply parts. If so, he can sell you the parts specifically suited to your motors.
And read the article...
Hope this hasn't been answered b4, but... Mach2 screen doesnt fit on my monitor except for higher resolutions,which in turn make it too hard to read.
Any ideas?
Worked fine on my laptop, but I...
Hi Dfranks,
I was guided by the design at http://super-tech.com. To me it just seemed simpler and something I felt I could take on.
Direct rack and pinion coupling.. seems ok.. I dont know what...
Hi, Dfranks,
I found myself in your shoes a while back. I saw a plasmacam advertised in a magazine and thought it was the coolest thing I'd seen in a long time.
Till I saw the pricetag that is.......
Could someone please recommend a specific limit switch for my plasma table?
I got sticker shock when I looked on Mcmaster carr's website. ($40,60 even $70 for some of them)
What do you guys use?...
I am going to use THC from BOB Campbell. But I'm not to that point in construction yet. I think I read a post saying he was out of town for a couple days... He will answer your email.
BTW, his THC...
I too looked at torchmate and all the others and could not justify spending nearly 10,000 dollars on a machine I intend to use as a hobby.
After reading about guys building their own I decided to...
Well, I fired up my future plasma table today.
Actually, I just ran two of the motors, but for me it was a milestone.
Hooked up the breakout board, geckos and had the motors sitting on the garage...
Im in Hudson
It's not connected to anything, its just on a board awaiting final assembly.
I plan to fabricate a cover for the whole thing when it's done.
Just dont want to have a shocking experience in the...
I am building my power supply for 4 axis stepper system.
It checks out fine at 67vdc.
How do I discharge the capacitor after testing, so I don't accidentally knock the tar out of myself?
Can I...
