Linear rail not sitting flat
I'm in pursuit of getting a really solid mechanical starting point, I've always just 'solved it in software' before. This time I'm aiming for a sub 0.1mm spread across the bed, if I can get it.
I'm edging closer with the creation of some jigs to make minor adjustments, but I think I'm now being hamstrung by a linear rail that just doesn't want to sit flat across the extrusion, as per the bed scan image. My feeling is that the low points are likely a cause of the linear rail not sitting nicely, too. As the image shows, the right (as you look at the front of the printer) Y linear rail now seems reasonably well situated/tuned in terms of the frame. Similarly, both corners of the 'left' Y linear rail are close to the same plane.
Any pro tips on resolving this? I'd like to avoid shimming if at all possible. So far, I've been using the standard guide rail jigs, loosening all screws off (except the rear end) and then untightening all the way, before gently tightening down (so as to allow the t-nut to move inside the channel and properly grip), before tightening fully and moving on to the next one. The thought process being that this would prevent any squeezing of the rails between the two end points. Perhaps I should also try starting from the middle and moving out in each direction one by one......
Move Out of Range Error When Measuring T1 Belt Tension
Hi Guys,
this error started popping up every time I try to measure the T1 belt tension on my V-Core 4 IDEX. It didn’t happen before, but it started after I installed all the updates. I have also re-tensioned the belts.
Please take a look at the error message in the attached picture. I have no idea what’s causing it. T0 works without any issues.

After underextruding, we now enter the era of bleeding and overextruding!
I am an owner of a Ratrig 3.1 400. About 6 months ago I had a failure (no pic) with my Rapido hotend. So I thought time for an upgrade with the toolhead v1.0.
Bought a new Rapido 2 too. (Bought 2 but that was my mistake. Anyway) tried to set it up but no luck. Massive underextrusion. MASSIVE. Just could not make it work. After a test print I came to the shop to find this. (Pic1) Replaced the whole thing and had another exactly same failure. I cleaned the first blob and put every thing together with new cables on the thermostat and ceramic heater. Ever since the change I have an extreme overextruding problem and the nozzle cannot keep preasure in the throat. (Pics 2&3) It drips if I try to heat it up. Oh and retraction does nothing at all. Also (and this is really weird) the temperature on the nozzle rises really slow... I calibrated every thing but to no avail. Any thoughts?...
Klipper reports: SHUTDOWN
Hi everyone. Just assembled VCore4 core XY, and going trough commissioning guide.After updating everything in “machine” tab, then successfully flashing control board and tool board and finishing the setup wizard get this orange message and after restart i get the red message.After firmware restart i get the orange one again.(apologies for speaking in so so simple words:). I auto reflashed control and tool board again but had the same messages.Im stuck , can’t figure out the problem and asking fo...
Dual_Carriage Endstop Always Triggered
Hey all,
I've been trying for a few hours on this one, can't work it out. Just going through initial commissioning on my IDEX 500. Stuck at checking the endstops, because dual_carriage is reading always triggered. The X and Y endstops are functioning perfectly.
It's not the wiring, it's wired exactly the same as T0 which works perfectly, and it's obviously just the short harness from the Omron to the port on the toolboard, so not a lot to do there....
Swapped out BL Touch for RatRig 5V Induction Probe
Since I was getting nowhere with the BlTouch issues, I decided to go the easy route and swap out the BLTouch for the RatRig induction probe.
Went to power on printer and got the standard error message: now I'm getting this,
Printer is not ready
The klippy host software is attempting to connect. Please retry in a few moments.
