New build with recycled parts on a ridiculous budget 120cm*60cm work area

**Neale** · 15-01-2018

Unfortunately I can't help much more with the LCNC side of things - I switched to Mach3 around a year ago and even then I was using a machine with single motors.

Could you possibly post the gcode, or at least the first few dozen lines, just so we can see what is triggering the error messages?

Ok some questions. Do you have dual homing working? How are you homing the machine?
I don't see a HOME_SEQUENCE = in your ini file.

In [TRAJ] you have COORDINATES = X Y Z I think it should be X Y Y Z Not sure on this now!!

Have a good read through this thread https://forum.linuxcnc.org/49-basic-...e?limitstart=0

No homing yet was homing by pressing the home button in Axis for each one and I also tried no forced homing as well. I've only just drilled for the limit switches and am waiting for M3's to come through the post to fit them. I've put them sideways on now with rollers before I have the switches at the end bad idea as someone pointed out and I was like it'll be fine lol.

As often happens I was wrong.

I would like to get a controller that does step generation on board so PC specs are irrelevant, linuxcnc compatible and of course Ethernet is there such a controller?

Yes Mesa 7i76e

I think you should take a step back and start with baby steps with Lcnc. Start by getting the homing sorted etc.
I have read your posts on the Linuxcnc forum and seen your ini and hal files they are different to the ones you have posted here try and be consistent with what you are asking.

I think your limits problem is that the machine does not know where it is, so get it homing first. I know where there is a working config for the 7i76e but it is for a plasma but is near enough.

The first ini I posted on linuxcnc didn't work I had set up A axis, the one I posted in the quote should have been the same one as I posted here but too early to check lol.

I've been looking at 7i76 for a little while but was confused on if 7i76 did step generation or you needed the 5i25 combo for step generation.

I guess what I'm asking is can I get away with buying the Ethernet version of 7i76 on it's own?

I'll get the switches on today hopefully my M3's have been shipped so should be today they come but I did try no forced homing as well as manual homing which I read should have made this go away but it did not lol.

When I press - on the manual move buttons for the Z axis should it move up or down? I'm guessing down at the moment mine moves up lol.

My friend keeps telling me to just use Mach 3 but if I do then I'd set up a pirate see if it works ok do some cuts then buy it and the inner tight guy inside me says just learn linuxcnc you idle twat lol and then the £200 you were going to use for Mach 3 will buy a 5i25 and 7i76 with the saved money ;)

Yes as I said just the 7i76e.

What do you mean by this it depends if you press on up or down keys

Also on the Z axis it should show -ve when going down. But in the the homing routine you can make it go either way it depends where the switch is ie you can change the travel to seek the switch out.

You are wasting your time playing without the homing switches on. As I said baby steps

-ve right I have it +ve at moment, and I have the router on the X axis going left -ve, right +ve and the Y axis -ve away from the front and +ve towards the front where I load.

As long as the M3's come today they're on ;) the wiring is already in place and connected to the BOB and spade terminal the other ends.
Stuck at home for an hour so can't play waiting for the guy to come see why my boiler stopped working it's going to be the thermocouple it always is. The house I live in was built in the 1920's and it's bloody freezing without heating lol.

The other error I kept getting was joint following error which I traced to the PC isn't fast enough really played with different latencies and ferror settings to no avail but I do know this PC is utter crap so will swap a different one in.
