    Many thanks Dharmic,

    This is already very useful.
    I had an old pc with windows XP on it, did a fresh install of windows on it and installed Mach3, so I have a clean situation here :-)
    The switches do work, the leds light up and a message about an home switch appears appears....
    However they don't stop the motors also when I click the "Ref All " Home button.
    So there must be a setting somewhere that I miss... this surprises me because I thought that with copying all the provided file from Omio, I would be all set.

    I think I saw a setting in Mach3 somewhere about automatic resetting; will try to find it.

    Regards, Robert

    EDIT: There is also a warning in Yellow: "Axis not referred to normal condition". I guess this is related?

    That message just means that at some point, you clicked the button to set the condition as "normal", and then changed something. It's the absolute worst feature in Mach3, and should be completely ignored, as it causes nothing but confusion, unless you are using it for a specific reason, and understand exactly how it works. It has zero effect on Mach3 functionality.

    It's also what happens when you reset (or start) Mach3 until you've done that ref axis sequence. Completing the sequence will fix it.

    The settings file from Omio worked fine for me. A couple of things to check then:
    1. Do the switches match up with the correct home points, ie make sure X lights up X, Y/Y and Z/Z.
    2. Are the motors in the correct connectors? Z is obvious, X moves the head across the gantry, Y moves the gantry itself.
    3. Are the motors homing in the right direction, ie do they head toward the switch or away from it?
    4. Are the switches actually engaging? My Y axis occasionally misses the switch and tries to keep going, a quick re-alignment and it's good again. You can confirm this either by switching to the diagnostics page once you start the ref all sequence, or just by using your finger to tap the switch once an axis starts moving and see if it stops then.

    To the best of my knowledge (which may be limited), the UK laws should be about the same as the Oz ones.

    First will be the Bed waiting for a quote on this ATM

    Hopefully it's not to crazy expensive....

    Having just done a bed upgrade, I'd go very carefully over what you hope to accomplish. It will improve Z accuracy by reducing flex of the base under tool load. But that's about it. The machine is still pretty lightweight so don't expect to see better accuracy, less vibration or any of that sort of thing out of it. If that's where you're headed I'd be putting the money into a mill or a steel construction router instead of chasing the Omio rabbit down the hole.

    Great... After a hard drive failure I had to reinstall everything, after that things started to make sense; i might have skipped a reboot step that caused me trouble also because before the Z moved in the wrong direction after hitting 'ref all home'.
    Now the only trouble was the switch for the Z did not engage fully at the right moment, adjusting the metal piece a little solved it. :-)

    Another thing if you don't mind .....
    I am using Fusion 360 at the moment to create G code, when I start the program it does not engage the spindle and when I turn the spindle on in advance, the program switches it of (and yes... there is 'S1000 M3' in the code).
    Any Fusion 360 users here and did you need to make changes to the 'Mach3Mill' postprocessor?

    I guess I need to learn about G-code, i found the 'G-wizard-G-code editor', is that something you would recommend or are there better options.

    Many thanks gentlemen for your help, its much appreciated.

    Regards, Robert

    EDIT: Commenting out M5 before S1000 helped to not switch of the spindle after manually switching it on.
    EDIT 2: After a little bit more searching I understood that M3 should turn on the spindle. But inputting this in the MDI and hit enter does not switch the spindle on. I can however change to speed that way, but only once. And I can switch off the spindle with M5

    1000 rpm is too low for these spindles, there may be some software limit like the soft limits on the axis. Others will know better. I use the mach3mill post in fusion exactly as it is, haven't changed a thing, and it works perfectly for me so far.

    Thanks Mmpie,

    Yes actually its S10000 in the code.
    I tried several things in the MDI but cannot make it work.

    Regards, Robert

    Edit 1:There is actually an error showing up in the status bar: "Scripter Compile error: in M3.m1s"

    Edit 2: Another problem solved: https://www.machsupport.com/forum/in...,20164.10.html
    I was suspecting that there was something wrong with the spindle speed, but after modifying the M2.m1s file as described in that thread: my worries regarding this are over :-)

    Does the program continue to run without the spindle running? Or does Mach 3 disconnect from the machine and trigger the e stop?

    Yes it continued to run without the spindle running, it was digging itself into the wood.
    I was just in time to hit the RED button :-)
    But I have it running now.

    One thing I noticed is that the sizes are of: instead of 80mm square I have 80,35mm.
    What could be the cause of this, do I need to tune the motors?

    I had some dimensions like that at the start when I was having running issues but everything I've bothered to measure recently has actually been pretty bang on in X and Y. Z is a different story altogether. I've since changed one of the Y bearings, stripped everything down, given it all a good clean and put in a new PSU so I don't know if any of those things were the cause and also haven't measured enough finished pieces of work to state that it's better now either.

    Mach3 does have an axis calibration page, plus full instructions in the PDF.

    However, you would have to check first how much backlash and flex you are getting.

    deflection can certainly do a lot of that if you're taking heavy cuts. If you re-run your finishing profile pass and you get new chips then just the frame flexing is causing your parts to be off size.

    Cutter size can also be a factor, my 6mm Omio 0flue cutters cut like .1mm undersize from the label.

    And keep in mind your CAM, if you have a tolerance setting there that could also effect your toolpaths. Worth double checking if you're not writing your gcode by hand.

    Wouldn't spending 6k on something like a tormach be a better bang for buck upgrade than a new spindle and bed for the omio?

    I must admit I'm a bit worried about the electrics passing the PAT test. They were exempt this year due to being under a year old but will be included next time.

    Hi mmpie

    I'm struggling for options I need a minimum travel of 400x300mm and 15000rmp on the spindle for the type of work I do and I won't get any change from 20k+ for a tormac and it doesn't meet my needs....
    Do you guys know of anything with those specs under 20k and under a ton ?

    I'm not 100% on these machines, I didn't waste much time looking at them as they were way above my budget. At the lower end there's the bigger 6090 machines which look quite substantial but still seem to have the crappy hollow bed. Over here we have some AXYZ machines which to be fair do look damn good.

    I was only planning on buying one of those cheap openbuilds router kits to dick about with and ending up spending way more than I intended on the OMIO OmioCNC report
