Final Step - Mesh Bed and Paneldue

[adalton5683]

First off, I have to say the amount of support and knowedge on here with the people actually working on developing this board and the software is astounding and I apprecieate that you guys put so much into your product.

I have hit every noob roadblock that a Professional Electrical Engineer can hit. lol Im in power so don't cast to much electronics shame on me. lol

Now the issues standing in front of my first print on this machine.
_________________________________________________________________________________________________________;

• Sub problem: (if you cant fix the main problem please help with this, but skip for now)
  Paneldue: Not so much preventing me but it doesnt work right, I get it to boot and connect sometimes but then doesnt show any real data. I tried to reformat my SD to 512 sectors but my mac doesnt like being that usable and cant figure out a tool that will do it. I have parallels running windows 11 and for some reason im having trouble getting the drive to be recognized in there after I formatted it in mac as FAT32(mac only allows 4k setcor for that format "Disk Utility" tool. (UPDATE: also while PID tuning my Hot end somehow now the paneldue doesnt even boot up with a splash screen)

_________________________________________________________________________________________________________;

Main Problem:: My bed offsets are not super great so im going to walk you through what I did to try and get my full range of motion and to be able to print where I say it should print.

I want to do center of the bed as 0,0. I will provide a graphic here showing my range of motion and where things are at endstops. I measured with calipers and I also used the DRO on DWC to measure.

• First I homed all, got to X Y endstops and then lowered the nozzle to where it would be touching the bed.(off the bed due to being at X,Y endstops.

• Then, I (to get the DRO to read right) sent the below command to get my zero to make subsequent movements useful in the readout. ( if ever hearing a click when I hit endstops like a skipped step I rehomed and rezeroed becaues I noticed it will allow me to go past the endstops in esteps count sense which moves my whole offset.

G92 X0 Y0 Z0

• Finally, I moved back up and over to where the nozzle touched the corner of the bed and repeated for the Probe. Both measurements were with the full diameter of the nozzle and probe in the limits of the bed so not to miss or clip the side when probing later.(so probable 2-3mm in from actual 0,0)

• • • The readout when the Nozzle was at Left Bottom corner:
      
• • • The readout when the Probe was at Left Bottom corner:
      

With a bunch of fiddling I think I have a good drawing of what the bed is like at home. NOW look at that first and then tell me why my offsets arent working. This is mainly due to my lack of understanding of how th offset system work in the Duet but I digress, I still need help. Getting just one print that is semi ok would be all the assistance I need then im going to not touch it short of pressure advance and Esteps.

Anyway, heres the layout:

• 

• 

Main Goal: Get this sucker to get me a mesh that gets pretty close to hitting the full extents of the bed. At the moment it probes about 2/3 of the bed. with I think these two parts making up the probing setup and I have tried other dimensions here just not sure I know what im doing. I forget if this one actually works but I have been able to get it to probe and some just dont work. I think rn im getting a no valid mesh error. not looking to fix that I just think I have the base understand of this wrong so some sort of help coming from where I am here with these measurements would be ideal.

the Nozzle_POS is its position when homes(the 2.5 is just a caliper measurement of the d of the end of the nozzle and same for the Probe.) Homed_Probe/Nozz. are the measurements when all axes are homed.

I think im struggling on where to put what offset. I started with just having the probe offset and then I put some tool offsets and it seems like there are more offsets than I can keep track of to make this not do bad stuff.

[Phaedrux]

Can you post your full config?

Does your actual config.g contain all those asterix? *

The offset for the XY axis to define the bed size is defined in M208 but your config.g snip doesn't include that.

Have you seen this page? https://duet3d.dozuki.com/Wiki/Centering_the_bed_or_setting_the_bed_origin

It may be easier to start with the 0,0 origin in the front left corner rather than the center. Then you can set the M208 minimum point as where the endstop triggers.

Example, if the endstops are on the low end of travel they may be a negative distance away from the edge of the bed, so your M208 minimum would be negative. It gets a little trickier when the ensstops are on the high end of travel. But your config snip doesn't include endstop config either so I'm not sure where they are located.

I should also mention that it is important to establish the correct axis orientation such that -x is moving to the left, +x is moving to the right, -y is moving to the front, +y moves to the back. All offsets will be based on this assumption of basic cartesian space.

The probe offset itself helps the firmware know where the mesh is in relation to the nozzle, but your mesh size will still need to be defined with that offset in mind if you want to make the most of the reachable area. The firmware will simply skip the mesh area that it can't physically reach.

I'm not sure what to say about your paneldue problem. Which SD card are you talking about formatting? The best tool to use for formatting is this: https://www.sdcard.org/downloads/formatter/ It will format based on what the card was designed to use and don't worry about it beyond that.

You don't mention what firmware version you are using but your config snip looks like RRF3.x at least. You need to enable the paneldue in the config and the Paneldue will need to have updated firmware to work properly. I would suggest that you should be using firmware 3.3 for both.

It would help if you could provide us with your full config.g, homing files, bed.g any other macros you use for setup. And the results of sending M122 and M98 P"config.g". That would give us a better idea of the state of your machine.

@phaedrux
So finally getting back to working on this. No those asterix are not in my config.
Also Here is my full config.
And, i ran the mesh on a area of X -115:115 Y-115:115 inc. 11.5 (using the gui to define the grid to probe)
the probe went off the bed for the whole first row in the fron so -115Y is off bed.

so i edited it the grid to X -115:115 Y-90:140 inc.11.5x & 23y and it didnt go off the bed but it skipps alot of points and i get this in the console.

In the middle of this i tried to see if i can print even with the bad offsets and it starts to print but about halfway into the first layer i get a heater fault and then it stops. So now theres another issue

When it says fault both the active and standby temps in DWC are set to my preheat temp. not sure if thats supposed to be like that or not.

For the grid point skipping that will happen when the probe can't reach the point you've set it to probe.

You'll need to set the grid size taking into account the offsets of the probe.

For starters though you should verify that you can actually reach the extents of travel you've defined with M208. With the nozzle at 0,0 which should be the center of the bed, can you actually move 115mm in every direction from there?

Have you measured the distance of the probe from the nozzle accurately?

For the heaters, they likely just need to have a tuning cycle.
