Don't mean to sound daft or noobish - been printing for a while now, but.. Explain white tape and the x-homing tab? :)

The x-homing tab is the little piece of plastic sticking out from the x-motor mount close to the threaded rod. It serves as the target for the IR sensor when homing the X axis. Depending on what P value you configure in your G31 command, the plastic may not reflect enough IR to trigger the IR probe, and then x-homing fails. Putting something reflective on top of the tab solves the problem. The current RepRapPro commissioning instructions suggest using a piece of silver foil.

I'm with you :blush: I actually didn't realise that the IR sensor was used there too - I had a few problems with x-axis homing, so I put in the limit switch and it seemed to get better - perhaps the shininess of the limit switch increased the IR return!
Wow - Can't believe that after essentially 6 months with the machine I'm still learning new stuff! :P]]> VortyZA Ormerod Sat, 21 Jun 2014 07:59:37 -0400 https://reprap.org/forum/read.php?340,333153,372592#msg-372592 Re: first print not gonna happen https://reprap.org/forum/read.php?340,333153,372592#msg-372592

I actually still have the same grinding problem with the x-axis. Added a limit switch (the original kit didn't have one) which mostly fixed it, but if the x axis is already at 0 then it just makes a horrible grinding noise when you home it. If I moved X in a positive direction, then homed X it would mostly work
....
I probably could have tried to solve the original issue, but was comfortable with the manual solution.

Did you put white tape on the x-homing tab?]]> dc42 Ormerod Thu, 19 Jun 2014 18:18:08 -0400 https://reprap.org/forum/read.php?340,333153,372142#msg-372142 Re: first print not gonna happen https://reprap.org/forum/read.php?340,333153,372142#msg-372142 The grinding does stop after it believes it's moved 200 after which it believes that x is at 0.
I tend to manually move the head and bed so that they are both at 0 while the Ormerod is off, then turn the Ormerod on. I send a G92 X0 Y0 to set the home for those axis. I manually adjust the z axis, then send a G92 Z0.
I also make sure that I never run a G28 again - remove it from all gcode files etc.
I probably could have tried to solve the original issue, but was comfortable with the manual solution. Only need to do it once per power cycle.]]> VortyZA Ormerod Thu, 19 Jun 2014 16:50:45 -0400 https://reprap.org/forum/read.php?340,333153,372121#msg-372121 Re: first print not gonna happen https://reprap.org/forum/read.php?340,333153,372121#msg-372121

If it is moving the wrong direction, check that you have the connector at the Duet side turned the right way as described here. Reversing the connector will reverse the direction of the stepper motor.]]> jstck Ormerod Thu, 19 Jun 2014 10:41:28 -0400 https://reprap.org/forum/read.php?340,333153,372001#msg-372001 Re: first print not gonna happen https://reprap.org/forum/read.php?340,333153,372001#msg-372001
G1 X60 Y20 takes me to the right hand corner above the back aluminium extrude. so X is correct. but why goes the wrong side?

any clues?

I don't think you have imported our Slic3r profiles. See: [reprappro.com]
Also, the current 0.65e firmware can be set to absolute or relative extrusion.

Ian, has that actually been tested? I think your 0.65e firmware is lacking a bug fix, to do with the handling of G92 for the extruder drive(s). I had to reinstate my fix when I merged your 0.65e into my 0.59.]]> dc42 Ormerod Thu, 19 Jun 2014 09:16:22 -0400 https://reprap.org/forum/read.php?340,333153,371964#msg-371964 Re: first print not gonna happen https://reprap.org/forum/read.php?340,333153,371964#msg-371964 Derrick_SA Ormerod Thu, 19 Jun 2014 08:55:35 -0400 https://reprap.org/forum/read.php?340,333153,371956#msg-371956 Re: first print not gonna happen https://reprap.org/forum/read.php?340,333153,371956#msg-371956

now the new problem is I cannot get X to home, it goes all the way the side, makes a horrible noise as it did not stop. and I have no idea why? yesterday, home X worked.

thanks for the info, I'll try in the morning. I'm also just for making sure gonna redo the Z Calibration and the Bed Compensation to make sure all that is still good. For now, a good night's sleep and tomorrow I will post what happens.

again thank you very much for the quick help I really appreciate it!
