Wire z max switch in parallel with second z max switch
Open, Needs TriagePublic

Description

This was brought up in an R&D meeting a while ago. If we add a second z max switch and attach it to the right z upper and wire the switches in parallel, the x gantry would have to hit both switches to home and subsequently level.
The parts that would need to change are z upper left and right, z max switch harness x idler. We would need to add another endstop switch, a length of t slot dust cover, 2x m2 inserts, 2x m2x10 shcs and m2 washers to the bom. The z max harness bom would need to include 2x solder sleeves, 2x purple faston connectors, and wire length

@west series not parallel

@tutley parallel since they are NC

The bom has been updated

  • M2 insert 4-6
  • m2x10 SHCS 4-6
  • endstop switch 2-3
  • m2 washer 4-6

The new dust cover has a drawing, we will need to make a pn for the cut length and update the bom when that is done

I have this installed on my machine and it has been working, however would it be possible , that once both end stops are triggered it ends the x-level sequence? Currently it does the same thing where it goes up and triggers both stops but then bounces a few more times. When it does that the x-axis can get out of sync and may not be truly level. I also think it is un-necessary for it to keep leveling once both end stops have been triggered.

@MikeR dont run the x level sequence just home the z axis. Running the x level disables endstops temporarily

@west So should we just get rid of the x-level function altogether?

west added a comment.Thu, Jan 17, 10:15 AM

@MikeR that is the plan, we are considering replacing the x level button with a rewipe button.

Ah ok gotcha. So just home the printer to get it level. check. Thanks for the info.

@MikeR how is this fix working out for you?

@west it has been working well for me now that I don't do the level axis and just home it.

So do we feel that this is good to go or do we need more testing?

tutley added a subscriber: marcio.Mon, Jan 21, 10:50 AM

@DaniAO i believe this is good to go, but with this change comes removing the x level button in the UI. which i dont think has been touched yet. @marcio can we remove the x level button and replace with the wipe nozzle button?

@tutley I belive the x level button has been removed in FW .77

@tutley Has already been implemented in .77, Please upgrade and give it a go.

@karrad nice, thx for the heads up!

Running FW .77 on Quiver 7 and these changes appears to have the x-level still enabled for the nozzle offset calibration.

@EricNugent: Yes, the X-axis will still be leveled prior to calibration. The only thing .77 removes is the button for initiating the X-axis leveling at other times. This is because X-axis leveling is now the same as homing Z, which already has a button.

@marcio sounds good, figured the dual switch was working better than running against the top of the frame and I didn't see it in the menu anymore so I thought it may have been missed.
