Fine tunning setup for Ender 5 plus

@aldiallo said in Fine tunning setup for Ender 5 plus:
when sending a M564 S0 nothing happens, same thing when sending the G1 Z1
What are you expecting to happen?
M564 S0 won't have any visible effect.
G1 Z1 would either move to Z1 or move Z by 1mm depending on if it's in absolute or relative movement mode.
Have you calibrated the probe trigger height?

After that you can fine tune with the method Veti describes.

Hi @Phaedrux
This is happening during the height calibration following the steps indicated on that link you sent, ok for M564 S0 but when doing the G1 Z1 I was expecting to see some movement at the motor level but nothing and also the G30 S1 reading where not consistent hence why I'm asking.
Thanks

Hello,
Still struggling getting this right as still not been able to get this completed without issues and still getting inconsistent values when triggering the probe to test the height, also seems like I screw up my homing setup as when homing the system goes off on the front left side.
Here's my homeall.g

check your probe using this
https://forum.duet3d.com/topic/6962/m48-measure-z-probe-repeatability-and-print-to-serial-output -
Where are your endstops physically located?
M574 X2 S1 P"io0.in" ; configure active-high endstop for high end on X via pin io0.in
M574 Y2 S1 P"io1.in" ; configure active-high endstop for high end on Y via pin io1.inThat indicates they are on the high end of travel, meaning based on a 0,0 origin in the front left corner the endstops would be at the right and back sides.
Have you leveled your bed and calibrated your extruder recently?
Have you done G29 to get a heightmap of your bed surface?

Hello,
Tired this on getting errors:
Z Probe already triggered at the start of probing move.

remove M401 and M402

Hi @Phaedrux
The endstop switches are in the right side for X and Y is at the back right side hand side when looking at the printer from the front.
When the head goes to the 0,0 origin the probe is outside of the bed, so my probe location based on the nozzle seems to be incorrect.

That's typical of using a high end endstop. You can measure your actual axis length by homing the nozzle to be where you want 0,0 to be. Then sending G92 X0 Y0, then you can send G1 H3 X400 which will move the x axis to the endstop and set the current position as the axis max. Whatever the X axis position is should be what your M208 maxima is. Then you can do the same for the Y axis.
-
I based the M208 maxima on the bed size so 350 for X and Y shouldn't that be correct??
Thanks
-
Measure as I described to find out
-
I did what you indicated, should I be seeing any results on the web interface? I've sent both commands and the print head moved to the end stop each time but that's it, not sure if I should have get a result for each axis that I should then input to the config.g file?!
on the tool position status I see X at 163,8 and Y at 174,4 and this is with the printhead at the endstop switch of both X and Y axis.
-
If you started at 0,0 and moved to the endstop from there then that's your axis length that should be in m208.
168 is far from 350. You moved the nozzle to the front corner of the bed and sent g92 x0 y0?
-
I did a home all first to bring the print head to the front left hand side and then executed the G92 X0 Y0 prior to running the G1 H3 on both X and Y axis as per your suggestion.
Something is not right but I don't know what.
-
Are you saying that homeall brings your printer to the front left side?
After you've done a homeall, manually jog the print head to place then nozzle at the front left corner of the printable area. Then send G92 X0 Y0. That way when you jog the print head over to the other end of the axis you'll have the actual length of the printable area.
-
When I do a home all the printhead moves to the right and back until hitting the endstop switches for X and Y the it moves to the front left side and deploys the bltouch, as the BLTouch is outside of the printable area I touch it when the bed is at the level of the ouch deployed tip is just after that that I send the G92 X0 Y0 and then the G1 H3 for the X and Y axis; I also tried moving the X to the right to get the BLTouch inside the printable area but still getting the similar results for X and Y in the tool status section.
-
Ok based on your homeall and your described behaviour your M208 axis length is way off or your steps per mm for X and Y is way off.
When you hit the endstops it takes the value from M208, so it thinks it's at 350. Then your homeall tries to move to the center of the bed but you say it's actually trying to move off the edge of the far left and front.
So how big is your bed actually? Do you have a ruler?
If you tell the printer to move X10 does it actually move 10mm?
-
The printable area is 350 * 350 * 400 but the physical size of the bed from what I've mesure is about 380 for X and 372 for Y; not sure what other Ender 5 Plus users using duet hardware are using but when I builded the firmware I entered 350 for X and Y and 400 for Z.
When I ask the printer to move 10mm for example x+10, it does move, but haven't mesured how much it moves thought but seems to me that it's moving around 10mm but will check that; now not sure if the issue is on the config.g or on the home*.g files
-
See if you can create yourself a diagram like this that shows all the relevant positions and distances and offsets for the XY plane.
Maybe capture a video of what you're trying to do to show what's happening. That can be a huge help for understanding what's actually going on there.
-
ok, will do that and report back.
thanks
