It will work , if you can see all the older pc's in the network already but the 7 machine cant ?
Try rebooting some or all the pc's after there all connected.
If win7 still isnt showing up or...
I feel the same way about this machine, currently machining out a cnc conversion for mine.
Had the hit the spindle wrench with a hammer a few times to reduce the play, will probably use a 1/4"...
I am not running the same machine but I do use Linuxcnc.
Linuxcnc runs in realtime on a PC unlike windows and mach3, you can download and use the setup cd or a memory card to run Linuxcnc without...
I have one, although I am blueprinting the machine for cnc.
Did use it a couple times so far manual but trying not to get it dirty until Im finished blueprinting.
The spindle motor runs very...
Heres a few things you can try, maybe one or all may end up being needed, try them separately.
Most breakout boards have LEDs on the outputs for each drive signal, if there not lighting up then...

This link has just what you need to figure out your needed power.

Since you say your new to cnc machining, I would say, stay away from anything more than about five years old, you will not be ready for all the pitfalls of older machines.
What are the settings you have for,
ports and pins: kernal speed
motor tuning: step pulse
motor tuning: dir pulse
It may not be running slower, if the machine is not binding up then it could be missing steps.
If you still need help, then describe the pc and software your using.
I forgot to ask is the steppers installed on the machine?
Did you measure the distance that it moved or just looking at mach readings ?
If you are bench testing it, try this, using a marker or...
I see what you are saying, the g203v that come direct from gecko are set at 10u, there is a note of internal jumpers that are not for users but could be used to make the g203v compatible with...
If the stepper motor is 200 steps per 360 degrees (most are) 1.8 degree per step then.
Motor steps x microsteps per step = steps per rotation, so if you input what you said you are using, it is (...
Not defending them at all, but it was probably cut on a cnc cold saw which is the fastest way to cut that material, you will probably not see the finish after its built and if the saw if setup right...
Maybe with some creative steps you can do everything with that machine you want. What I am talking about is the methods you use to cut different materials and within the limits of your machine.

Yes, that is where the rails would go.
The red arrows you would remove ( current linear bearings )
The blue arrow is the part that will need machined or replaced so that 4x new linear bearings...
You would need to have/or machine the blocks that are on the machine now (the part with the switches on it) or make a new one.
Looks like theres enough material to machine pockets out for the new...
First identify the problem axis. (sounds like Y but could also be X)
There should be a setting in the software to change the direction, if not and it uses stepper motors you could reverse the wiring...
I agree supported rail could help.
Heres one type of supported rail I found on ebay, you will probably find out you need to replace x,y and z if there all unsupported.
Linear Bearing Slide...
Was thinking you had something to setup mach after I typed that, all those setting could take a long time to figure out.
There is a few settings in linuxcnc you will have to edit manually, the one...
Maybe a picture and part number of the break out board would help.
Not sure how it worked in mach. Ive circled settings that dont look right.
You have 1 for this output pin but its probably 6...
Theres a few settings in linuxcnc you will have to manually change, maybe that is why its not running.
First what is the parts you are using and will probably need either screen shots or settings...
A = step 8 | A= dir 9
B= enabled | B step 16 | B dir 17 | step port 1 | dir port 1
Ports and pins, page 3, picture 2 on the pdf , although they show B disabled in there picture since its not used...
That was regarding 3 phase hybrid steppers and drives.
Even looking at my regular steppers with an amp probe just now they also draw more running than holding, and even more power switching...
Heres the 105c caps in stock value and a little higher capacitance.

Different brand too, new unused caps can go bad sitting on the self btw.
Its rating is at what you said your reading was, from my experience a voltmeter may read a little high when a power supply...
The drivers typically go shorted when they go, internally they may have a fuse/fusable link but it should be last to go.
Maybe time to remove a cover and inspect one, ripple could cause heating and...
Besides losing a connection inside the driver itself , which would require you to remove the cover and inspect the boards for bad solder connections or a fusable link.
The only other thing I...
I would suspect the board with all the fuses has a problem, cant see all the drives going bad at the same time. This is your common connection between all the drivers.
Plus each driver is fused from...
