      @fcwilt My BLV rebuild of my old Anet A8 had linear rails. Marvelous kit, those. I still have them, and putting them on this POS seems possible with a little elbow grease and a drill press (both of which I have).

        @fcwilt got it, ship me the X and Y code please. I'll test Z right now to confirm that the changes accomplished what I may have to use to correct X and Y if they aren't up to snuff.

          @mac said in I could use some help:

          @fcwilt I'm not opposed to buying a decent bed. Given that the one I have on this printer now has failed the PID tests horribly, I'm looking for a good bed. Any recommendations you can provide (preferably links that will make you some money), would be appreciated.

          I know very little about your type of printer. I know that some popular models have upgrade parts available from different sources.

          I just upgraded the bed on my E3D Tool Changer printer with a bed from Mandela Rose Works (I think that is the correct spelling).

            @fcwilt Z went up, and then it went down. It sounded like a real printer / that's a first. My guess is, it's about 30mm off the bed at the moment. I think that was a choice in the RRF? That the first time Z homed, it stopped at 30 above?

              @fcwilt I'll google them and go from there.

                @fcwilt if you have the time, please send the X and Y code, then be off with you to your own time, and thank you in advance.

                  OK

                  Homing X should look something like this:

                  G91
                  G1 H1 X-230 F3600
                  G1 X15
                  G1 H1 X-10 F360
                  
                  G90
                  G1 X110 F3600 ; this just moves X to the centerline of the bed - doesn't matter where - it can be any place at all that suits you.
                  

                  Homing Y should look something like this:

                  G91
                  G1 H1 Y-230 F3600
                  G1 Y15
                  G1 H1 Y-10 F360
                  
                  G90
                  G1 Y110 F3600 ; this just moves Y to the centerline of the bed - doesn't matter where - it can be any place at all that suits you.
                  

                  Now I would do homeall.g like this:

                  M98 P"homeZ.g"
                  M98 P"homeX.g"
                  M98 P"homeY.g"

                  It is not as efficient as it can be but it does re-use the code you already have in the other axis homing files.

                  Now I have no idea what kinds of speeds your printer is capable off. I just used F3600 and F360 since they should be workable and safe. Feel free to pick other speeds as suits you.

                      Did you get Z homing to work?

                            G1 H2 Z5 F3600           ; lift Z relative to current position
                            G1 H1 X225 Y225 F1800    ; move quickly to X and Y axis endstops and stop there (first pass)
                            G1 H2 X-5 Y-5 F3600      ; go back a few mm
                            G1 H1 X225 Y225 F360     ; move slowly to X and Y axis endstops once more (second pass)
                            G90                      ; absolute positioning
                            G1 X-10.875 Y4.375 F3600 ; go to first bed probe point and home Z
                            G30                      ; home Z by probing the bed
                            

                            This is the code that's in the system. It doesn't look like your suggestion? So I'm not sure how to proceed.

                              As I mentioned that is the code for homing with a Z probe.

                              You have a Z endstop switch as well so you can use that, instead of the Z probe, and get quicker and simpler homing.

                              We discussed getting rid of that code and replacing it with my code.

                              What happened to doing that?

                                    This is what I put in homeall.g's place.

                                    So you where showing me the code from homeall.g - I misunderstood.

                                    That code you now have will work fine IF the individual homing files work.

                                    You can strip it down to this:

                                    ; homeall.g
                                    ; called to home all axes
                                    
                                    M98 P"homeZ.g"
                                    M98 P"homeX.g"
                                    M98 P"homeY.g"
                                    

                                    But don't test it until you have verified that homing each axis by itself is working.

                                          OK X is behaving very strangely.

                                          But as to Y:

                                          Is the Y endstop at the front of the machine or the back?

                                            @mac I see that the Duet Mini 5+ does not have on-PCB pullups on the IO pins.

                                            You need to go to the RRF configurator and select "Active low with pullup" if you are using normally-open switches connected to ground as endstops.

                                            Without a pullup, every time a stepper motor starts moving, your machine will start to get signals indicating the endstop switch is being pressed.
