Sovol SV08 Multiple Motion System Upgrade.

[dwuk3d]

@dwuk3d
Ps/ the 500's relate to the fact that orca slicer is putting F30000 on zhops for some reason.-
With slower speeds like between F3000 and F13000 for the actual print moves.

I might try reducing the F30000 to say F600 in my post processor tomorrow to see if somehow that is getting picked up and overriding the later feedrates.

@dwuk3d are you using mesh bed compensation? If so, is it applied to both tools or only the first one?

[dwuk3d]

@dc42 no not yet.
All i am doing at present is tap probing two points per print head (one in the centre and one by the prime tower) and then switching the Zhopper motor offset to the appropriate height in my tool change/priming macros when switching between priming and printing.

Once I have sorted out to speed issue doing independent mesh compensation is what I plan to do - probably using a SZP on each print head.

In terms of the speed problem my next steps are:

1. Try changing the zhop speed down from F30000 (which should be being ignored by the zhoppers, but used for the xy / uv / wv moves, but not extrudes)
   Update - changing ZHop + ZHop Travel speed from F30000 to F3000 - no impact.
   There are still travel moves of F30000 - so next step to change all of those over to F3000
   Update2 - Changing travel moves to F3000 no effect - 2nd tool, 2nd layer still too fast

Example Layer switch on T2 - where printing is very fast

Note they both specify the same feed rate

2. Try reducing the overall speeds and accelerations - firstly globally, but might then try changing it dynamically between travel and extrude moves to see what happens
   Update - trying M203's before every feed rate change - examples

Update - 2nd tool still too fast even with M203's before every feed rate change.
Next test - changing the limit on M203's to F12000 vs F21000 to see if that slows down T2/T1.
Update- still not working - T2/T1 still too fast.
Next test - changing config.g to lower all Axis speeds from 21000 to 12000 - so see If that at least slows down the layer2 extruder moves on T2/T1
Update - T2/T1 still too fast
Next test - changing config.g to lower all Axis speeds down to 6000, plus also change all G1 F30000 to G1 F3000
Update T2/T1 still too fast - no extruder moves are nice and slow - but extrude moves are still far too fast and don't seem to be respecting any sort of feed rates.
Maybe somehow to extruder federates are being respected rather than the motion ones,
Next test - Trying halving all extruder rates

That didn't work either - but finally I think I am getting somewhere.
M203
Max speeds (mm/min): X: 6000.0, Y: 6000.0, Z: 600.0, U: 6000.0, V: 600.0, W: 600.0, A: 600.0, B: 600.0, 600.0, E: 1800.0:1800.0:1800.0, min. speed 30.00

I have slowed down all of the max speeds on the UV&W axis by a factor of 10 using M203's before every feed rate change - its now moving at a snails pace - but seems to at least be taking notice of the max feed rates now and going at a more reasonable pace for the extrude moves.

Interestingly it seems to be moving faster on the W than the V axis for these types of move

        G1 A{global.aPrimeOffset} F300
        G1 F2000
        G1 W{param.W} V{param.V} F2000

        G1 W{param.W-2} V{param.V+param.S/2} 
        G1 W298 V295 F2000

Example main printing GCODE that's finally running at a controllable pace - a bit slow - so will probably try just dividing the speed by 5 for extrude moves only next.

3. Try some simpler models with just 3 squares - and try various combinations of 2 or 3 in different orders to confirm whether it is the ordering of tool swaps that is impacting which gantry runs too fast.
4. Try later firmware as I am still on 3.5.4

[dc42]

@dwuk3d maybe it's treating U and V as rotary axes in the feed rate calculations. What M584 command do you use to create U and V? What is the response when you send M584 without parameters?

[dwuk3d]

M584 X0.3 Y0.4 Z0.1:0.2:0.0:1.3 U1.0 V1.5:1.6 W1.1 A1.4 B0.5 D1.2 a0.1 b0.2; set axis mapping

NB/ I have duplicated 0.1 and 0.2 on dummy a and b axis at the moment to try and overcome my layer shifting problem.
Not sure if they are still needed as I might have found a workaround by surrounding my G1 Zn layer changes with T-1, M400, Tn.

Output from M584 as follows.

Driver assignments: X0.3 Y0.4 Z0.1:0.2:0.0:1.3 U1.0 V1.5:1.6 W1.1 (r)(c)A1.4 (r)(c)B0.5 (r)(c)D1.2 E121.0:122.0:123.0, 9 axes visible

NB/. A,B and D are my Z hoppers - not the motion axis

I think I can getting closer to understanding this issue which seems to be that the the 2nd motion system used in the print - the Extruder moves around between 5 and 7 times faster than the feedrate you specify in the F parameter on the G1 command.

I'm just about to try a print with my original settings and speeds - but with in the case of the print where the M596 P0/T1/T2 motion system comes second in the print - with all speeds correct, apart from the G1 E moves - which I am adding a F parameter - with the required feedrate divided by 7.

UPDATE: I think dividing by 7 for the E moves is a bit too much - but also the normal non extrude moves are now a bit fast too - so I probably need to divide the speed on those too.

[dwuk3d]

@dwuk3d Further update - have moved on to testing with the same shape on each print head and I think the its more complicated that just multiplying the feedrate.

When doing diagonals to fill out a square the speed might be getting faster in different parts of the diagonals

Will switch over the print so that the X&Y M596 P1 motion system comes second next to see if I can work out a pattern.

Further update - when printing squares - I changed the print order so that T2 white came first - and it still prints too fast when I don't divide the speed - so I may have been wrong about thinking it relates to the motion system and tool first used order.

So will continue with my investigations for now on the basis that the issue relates to the U,V & W Axis.

[dwuk3d]

@dwuk3d Decided to upgrade from 3.5.4 to 3.6.0

All went fairly well - homing not quite the same - even though I am using optical sensors all round with no sensorless homing.

I had to make a small adjustment to my U axis homing - just positioning the A Axis (which is the lifter on the WV extruder - which the UV extruder homes against.

Probing and alignment worked ok.

Started multiple motion system 3 colour simple squares print that has worked on on 3.5.4 - and for which I was just trying to tune speed adjustments.

T0 worked ok.
T1 priming worked out - but printing out of the box didn't UV movements which should have formed a square shape just formed a diagonal line.
T2 had the same issue - so not sure what is going on.

It can't be a general movement issue - as things work fine when moving around and doing alignment / homing etc.

Picture showing square working ok from T0 - should be two more from T1 and T2 - The T2 one in white is shown roughly where the white bit of plastic is - which was its attempt to draw a square.

Both of them just came out as diagonal lines - they should have been like this

[dwuk3d]

@dwuk3d Managed to get a print out of my WV axis on 3.6.0 - but I am getting unreliable homing on UVW, plus the W motor stopped working when trying to do my W homing.

Moving V was moving out in the W direction too.
G1 W-1 didn't move it
G1 H2 W-1 moved W - then after that G1 W-1 seemed to work.

I wonder if there are still issues on 3.6.0 with remote tool boards - I have a 6HC as the first board - the 0. drivers, and a Mini5+ as the 2nd board - the 1.0 drivers.

I think I might have to go back to 3.5.4

Oh dear - attempt to revert back to 3.5.4 failed now getting no response over LAN and no flashing lights - will have to dig out the serial/usb cables.
Last time this happened I had to reflash the Mini5+ board using a PC - which is quite inconvenient as it is hard to get a USB cable into that board.

@dwuk3d this thread is far too long to use for raising firmware issues. Please start a new thread for each distinct issue.

[dwuk3d]

@dc42 i didn'r think it was worth raising issues until I went to 3.6.0.

I tried 3.6.0 yesterday and today and have got a more fundamental issue with 3.6.0 which I have raised as a separate thread.
Once I have resolved that (or found a workaround) I will retest other issues and if they still existing raise them as 3.6.0 threads.
