@phaedrux OK, thankyou, I have not done an extruder calibration test, just used recommended flow rates and such...

@phaedrux Yes

@jsinicro
If you have to push the filament to make it work again, you might have a problem with the PTFE tubes in the hotend.

@jsinicro any thoughts on the 2 printers I've mentioned above?

@dc42 That will be awesome, the slicing software would be interesting on how to handle that.

@jsinicro said in Understanding Height Maps:

so one can put basic math functions and variables in the G-code? are there examples on this?

Don't let the extreme skew of the heightmap image surprise you. It's a very exaggerated view to highlight the surface. That said, you've got nearly 4mm difference between the highest and lowest point. Mesh compensation MIGHT be able to correct for that, but that would also mean a very lop-sided print if it could.

Getting the bed manually squared to the print gantry is still required for best results. How exact it needs to be will depend on how exact you need your printed parts to be. Normally within a layer height or two is acceptable deviation.

I assume you mean this?

6-way barrier strip: two pins for main VIN and GND; two pins for the VIN and GND supply for the OUT_0 terminals; and positive and negative OUT_0 terminals. OUT_0 is intended to drive a bed heater. The ground side of OUT_0 is switched by the mosfet and the positive side is protected by a 15A fuse. If using the OUT0 terminal to drive a SSR, take note that their polarity is opposite to the polarity of the VIN terminals.

What it means is that the + and - terminals for OUT0 are reversed compared to the terminals for VIN and OUT0_IN

@mrehorstdmd Thanks for the post above. Found it looking searching for just such info, ordered SDF DF184S for my modded Creatbot f430. No-smoke, great!

BTW- my Keenovo was installed on the bottom of a glass bed with their adhesive and silicone 5? years ago. Never had any issue with oxydizing of the glue. Finally though some of the coils died. Waiting for the replacement.

@phaedrux OK Thx, I did have S1 before.

@dc42 thankyou

@jsinicro said in how to move nozzle to home position:

@deckingman Yes, I thought about it later G1 X0 Y0 Z0

You may not want to move to Z0 since that would have the nozzle touching the bed - and if things are slightly off - hitting the bed.

You might consider something like Z10.

@fcwilt thankyou

Could you show some photos of the printer to show how it's laid out? It's a little confusing to understand.

@jsinicro said in 2nd independent Z-Axis labeled V Homing failed:

It would be my goal to have both tools to extrude simultaneously on the same part

Good to hear you've sorted it out.
To print simultaneously, you'll have to be patient. The firmware isn't yet able to do it.
Can't you print a mold and do fibre/resin casting?

@dc42 OK, thankyou. I have a CNC machine as well and it doesn't force the homing sequence on every power on, that's why I was asking. I didn't realize but what you said makes sense, I think I should home the CNC machine every time as well.

@jsinicro OK, just tested this, now the probes are deployed independently however when I probe the V axis which is the 2nd X axis eventhugh the probe triggers and the axis stops moving I get a response G28 V Error Homing failed. Can this be debugged or any suggestions. This is the probingV.g file: -I changed the file that was generated, maybe I need to put the original back as now I have the probes working?

@dc42 Yes, all are running independently now and everything is stable, thankyou.

@dc42 Yes, thankyou.

@jsinicro I suppose I could use the JST high amps step that down and connect both
