New experimental firmware 1.19beta9

dc42

The bed probing code was reworked in beta 8 but there was no intentional change in functionality apart from adding the option of manual "bed probing".

In beta 9 the only change is that on a Cartesian printer, if you have used M671 to define the bed leadscrew positions, then the final G30 command with the S parameter computes the leadscrew adjustment instead of doing 3, 4 or 5 point bed compensation.

Eddie, what happens if you command bed levelling from PanelDue and then look at the Console page? When you say 'bed levelling' do you mean G31 auto calibration, or G29 mesh bed compensation?

same as cubexupgrade cant get the X and Y working
on a corexy
they are swaped

DjDemonD

Yeah I just noticed this on my corexy, had to swap the y motor direction in the end. Working now.

@dc42:

Lars, thanks for running that. If you want to try fixing it yourself, I believe the issue is with CoreBaseKinematics.cpp line 47. It should call ZLeadscrewKinematics::Configure not Kinematics::Configure.

Did the change you suggested and got it working:

M671
Z leadscrew coordinates (250.0,560.0) (560.0,-10.0) (-60.0,-10.0), maximum correction 0.50mm
G32
Simulated calibrating 3 leadscrews using 3 points, deviation before 0.098 after 0.000, corrections: -0.189 -0.065 0.118

Found one small bug in ZLeadscrewKinematics::Configure:

bool seenS;
gb.TryGetFValue('S', maxCorrection, seenS);

Need to initialize seenS to false or you will not get reporting of current settings…

this dident work for me
Important! On a CoreXY machine, you need to either swap the X and Y motor connections, or set the Y axis factor to -1 in the M667 command. Similarly for CoreXZ and CoreXYU machines.

Eddie, what happens if you command bed levelling from PanelDue and then look at the Console page? When you say 'bed levelling' do you mean G31 auto calibration, or G29 mesh bed compensation?

The console says nothing more after successfully connected to the network and showing the ip address.
strange.

I am not sure what the bed leveling button issues as a leveling command; I meant to ask that -

WebUI says "Auto Delta Calibration" (button) clicking the drop-down there are options, of course, Run mesh, Show Mesh, etc… Selecting these says there is no valid grid defined for G29.

Here is the contents of my bed.g, - OH, I guess this is G31, Auto. Tthe Paneldue and WebUI appear to execute the same function when pressing the button.
Can try other betas if you want me to. This is the same bed.g that has been in use since I owned the board.

; Auto calibration routine for delta printers
; Before running this, you should have set up your zprobe Z offset to suit your build, in the G31 command in config.g.

The G1 X0 Y0 Z150 F1500 no longer does anything or does not get executed.
Let me try commenting out that line real quick as a test..
– Commenting out the G1 line had no affect.

Let me try removing F30 P15 line.
Ok, commenting G30 P15 X0 Y0 Z-99999 S7 out, the script completed.
However, it never reports the before and after settings. So that line is probably where the problem is.

One last note:
Hitting the button from the paneldue does not cause an AJAX error on the WebUI. Whereas, clicking the button in the webUI to level the bed, will generate an AJAX error, on the Paneldue console it will say "connected to wifi network" and show the ip address it obtained, again. So something restarts when issuing the command from the WebUI that does not restart when doing it from the Paneldue. I gunna say the S7 parameter is what causes something bad to happen. The head moves to that location.. the very next thing is S7.

Let me know if there is more I can do.

hello after firmware update for 1.19beta the wifi module stoped responding,
Upload successful
WiFi module started
Error: Failed to initialise WiFi module, code -10
[ERROR] Error: Failed to initialise WiFi module, code -10

what can i do to fix this?
thanks in advance

A Former User

@tape: Do you mean "update from 1.19 beta"? Please check if all the firmware versions are correct or just try flashing Firmware/Server again.

My question:
In standalone access point mode (M589 S"DuetWifi" P"Silverspoon" I192.168.1.1 –> M552 S2) I can connect to the DuetWifi.
DHCP works as I get an IP adress but "ping 192.168.1.1" leads to "Destination Host Unreachable".
So I don't have access to the web interface. However the Web Control was accessible before when connecting to a known network (mode M552 S1).

lars

@lars:

I get some weird behaviour when using the web interface Machine Control with second tool.

Test Setup:
Disable all tool change scripts.
Run home all (Script will inactivate both tools with T-1)
Switch to T0 and move it to -33 as I don’t want T1 to crash into it

Switch to T1
X -1

T1 moves to min position (-5) and stops to respond to X interface commands.
I can however move T1 using the g-code console: G1 X10 will move t1 to X10 absolute.
Once I have issued G1 X10 in the g-code console I can use the interface Machine Control again to move X.
If I switch T0 and back to T1 the first x command in the Machine Control will move T1 to min position (-5) and stops to respond to X interface commands.

I have tracked down this bug to how currentUserPosition is used in GCodes::DoStraightMove. After tool switch to T1 and a G1 X-1 is issued it currentUserPosition[0] (x-axis) has the value of T0 X (-33 in the quoted example). It will take this value and substract 1 for relative move of X. Later in the code this value (-32) is mapped to U and limited to min value -5 (So T1 will in my case move from 525 to -5 when issuing a relative move G1 X-1).
Either the currentUserPosition must be updated on tool change so that the X reflects the mapped tools coord or the mapping need to be done in DoStraightMove… Whats do you think David?

There is a bug that is causing message packets to be lost when the WiFi module is put into access point mode. We haven't tracked it down yet. Some other projects are having the same problem, so it looks like the bug may be in SDK code that is closed source.

Thanks for investigating this. I'll take a look at it tomorrow. I thought we were already updating currentUserPosition on a tool change.

Need to increment numXAxes, numYAxes in GCodes::ToolOffsetInverseTransform! Added in code below.

		const uint32_t yAxes = reprap.GetCurrentYAxes();
		float xCoord = 0.0, yCoord = 0.0;
		size_t numXAxes = 0, numYAxes = 0;

Before going to beta9 I was on beta6 which worked ok for "auto delta calibration" button on the WebUI and on the Paneldue but wifi did not work reliably.

Testing betas 6, 7, 8, 9, my problem with auto delta calibration began with beta8. Any suggestions?

Changing bed.g, allows the calibration to be reported, but don't think it gets stored..

;G30 P15 X0 Y0 Z-99999 S7
G30 P15 X0 Y0 Z-99999 S-1

However, if I reverse the commands so that S-1 is done before S7, I get new message

G30 P15 X0 Y0 Z-99999 S-1
G30 P15 X0 Y0 Z-99999 S7

"Bed calibration error: 7 factor calibration requested but only 0 positions provided."
– I guess S-1 prints the values then empties the memory.
-- S4 behaves the sames as S7.
