They are e0temp and e1temp, as labelled on the board.

It seems that build has an issue with the tool offsets if you use an tool changer.

If I do a tool change directly from T1 to T2 for example then the printer crashes because it want to recover his old position.
If I do a tool change from T1 to T-1 and then to T2 everything is fine.

It looks like if I do a direct change there is a issue when the tool offsets is deleted or applied. I am not 100% what wrong

smoki3

So I think I figured out the problem:

It seems that between the last move of tfree0.g and the first move of tpre1.g it is doing a recovery of the old position ( G1 R2).

@dc42

Does it behave differently from firmware 2.03? There shouldn't be a difference.

smoki3

@dc42
It was definitely not like this on 2.02 and the older 3.0.

And its a really wired behaviour. Because I use:

The I only expect that only a X movement is done while the start of the tpre1.g but it first moves in X and Y.

If you read the firmware update motes for 2.03 you will see that tool offsets are now applied during tfree and tpost (but still not in tpre). Does that explain the issue? You can use G53 to prevent tool offsets being applied.

wilriker

@dc42 Small hijack here: I realized that tool offsets are not applied for G32 when doing manual bed leveling assist. Is that how it is supposed to be?

wilriker

(I think) I found a bug with PID tuning. When I try to run M303 Hn Snn it will always give me

Error: Heater is not ready to perform PID auto-tuning

I tracked it down to Heater.cpp:CheckGood() where it says

return GetMode() == HeaterMode::fault && CheckProtection();

and I think the first comparison should be != or the heater is only good it if actually is in fault state.

P.S.: Recompiled with != and at least it started the PID tuning - not sure if it will stop heating before the thermal cut-off will activate though, yet.

EDIT 2:
I more or less successfully ran a PID tune for my heated bed. But: in the end it gave me

Warning: Auto tune of heater 0 failed due to bad curve fit (A=238.4, C=854.2, D=0.5)

This was the misleading result of Heater.cpp::SetModel() returning GCodeResult::warning due to the "heater appears to be overpowered" fact but LocalHeater::CalculateModel() only checks for GCodeResult::ok or anything else and in the latter case (including the GCodeResult::warning) it will issue the above warning message to DWC.

And one more EDIT: it did not output the

Warning: heater 0 appears to be over-powered. If left on at full power, its temperature is predicted to reach 263C.

as part of the Auto-Tuning procedure.

That change I now, as you can see in my script they already include G53 commands in the tfree.g

But the problem is:

Look at the last movement of my tfree.g: It move to G53 Y165 (no tool offset)
Then the script is finished. Then it starts with the G1 X76 in the tpre (still no tool offset)

What I then expect is that the printer is just moving form G53 X0 (from the tfree.g) to the G1 X76.
But it is also moving in the Y axis.

For me it sound like more that it is a bug of this change:

What new:

Restore points (created by G60 and created automatically at the start of a pause or a tool change) now have their coordinates stored independently of any workplace offsets. So if you create a restore point and then change the workplace offsets, when you go back to the restore point it will go back to the same machine position regardless of the change in workplace offsets.

It seem like it is restore the old positions from the tool coordinate system during a tool change. Because also tries to restore the Z position during the tool change.

Means if you positioned the tool with G53 Y165 in the machine coordinate system then the tool stays at Y210 (depending on the tool offset) in the workplace coordinate system. Then you drop the tool! With the next movement of the tpre.g it tries to move with the machine cordnatesystem to Y210. Which is wrong at this point because for the tpre.g no tool offset is applied and it should just move in the axis you are calling.

There is a workaround for this issue:
If you put in the tpre.g the same command (G53 G1 Y165 F25000) on the first place then the printer is just restoring the Z position and the you can start with the tool change

Thanks, I've corrected the source.

Please clarify. Are you saying that the G1 X76 command in tpre causes a move in the Y direction too? If so then this is certainly a bug. The coordinates stored in the tool change restore point should only be relevant at the end of the entire tool change sequence.

smoki3

@dc42 Yes the G1 X76 also do a move in the Y direction. Also the Z axis is moving.

It restores the coordinates where the nozzle was before. The reference point of the printer tries to reach the point where the nozzle was before.

The only way actually can avoid this behavior is to put also a G53 G1 Y165 into the tpre.g script. Then only a Z move is done (but also this movement shouldn't be done).

Have you also seen my edit if the post regarding misleading message output?

smoki3

@dc42 I switched now back to 2.02.

Here is everything fine. Also 2.04 and 2.03 has this issue. I tried also the old v3 build from the dropbox. Here also everthing is fine.

I assume that it has something to do with the commits from May 25th.
I will later do a build an try it out

I was trying to build a older build but it seems that it's necessary to build wifisocketserver. But I don't geht it to build in my mac

dc42

This is now on my list to investigate, and fix in 2.04 if I can confirm the problem.

You don't need to build wifisocketserver, you just need the include directory in it to be present in the Eclipse workspace.

You don't need to build wifisocketserver, you just need the include directory in it to be present in the Eclipse workspace.

I always get this when I trying to compile from a older source. If I try the actual branch everything is fine

../src/Networking/ESP8266WiFi/WiFiInterface.cpp:1857:10: error: 'APIN_SPI_MISO' was not declared in this scope

make: *** [src/Networking/ESP8266WiFi/WiFiInterface.o] Error 1

wilriker

@smoki3 You have to make sure that all of the repositories are at about the same point in time to compile. Most of the times having all repos except RepRapFirmware at the latest commit works but every once in a while there are bigger changes across repos (as in the case you show where some constants had been renamed) that require you to revert the according repo (I think it is CoreNG in this case) to a commit prior to the breaking change.
