RepRapFirmware 3.0beta 11 released

found the zprobe_in to zprobe_mcu .. just 10k trough and 2n2 down .. so def port configuration missing

and I also found the commit that introduced the bug:

src/Endstops/LocalZProbe.cpp:42

https://github.com/dc42/RepRapFirmware/blame/c25d73194252791ceb479ced79ffc77b31c810fe/src/Endstops/LocalZProbe.cpp#L42

you switched it from PinAccess::readWithPullup; to PinAccess::read;

A Former User

This will probbly work ok with bltouch v2 or v1 as they have 0/1 output, v3/v3.1 is open drain output so it can only pull low. Not sure why you switched from readWithPullup to read, but maybe create a new probe type with pullup, or should we add external pullup if this is to remain without one on the port?

@smece sadly, I saw your posts 3 minutes too late :p.

Thought my errant height map was a fluke due to a part swap. I dug a nice groove into my test spring plate (luckily I always use a sacrificial test plate whenever I change anything on the printer, hardware or software).

Moving back to 10 brought everything back to “normal”.

@smece said in RepRapFirmware 3.0beta 11 released:

so I'd say ZPROBE.IN is HIZ at this point and there is no pullup enabled... I don't see on schematic where zprobe_in becomes zprobe_mcu, are you using external pullup or you just need to configure it as in with pullup enabled .. anyhow .. there's no pullup on zprobe.in with beta11

Thanks for tracking this down. I removed implicit enabling of pullup resistors in beta 11 because it meant that you couldn't turn them off. If you want to enable the pullup resistor, you need to be explicit by using C"^zprobe.in" in your M558 command.

The BLTouch that I test with is the older version that drives the output high when triggered, that's why I didn't see the problem during testing.

I'll update the documentation to make this clear.

Perfect, this solves the problem. Everything works ok now.

I just installed RRF3.0beta11 on my DuetWifi2, and I have troubles configuring Fans. In my config.g file, I have:

M950 F0 C"heater1" Q100    ; Fan 0 (water pump) is connected to heater 1, PWM at 100Hz
M950 F1 C"heater2" Q100    ; Fan 1 (Berd air pump) is connected to heater 2, PWM at 100Hz

; Tools

But I don't see any fan controls in DWC2... What I missed?

I also would like to know:

how to setup thermostatic control for a fan
how to name a fan

Thanks,

PS: the tool is working fine.

I also have the homing issue G0/G1: insufficient axes homed.

But it does not happen all the time. It can home fine, then it does not. I can't find a pattern, it can happens at different stages...

Thanks for you help.

@fma You need to put your M584 before M667 and M208. Look at the order dependencies here https://duet3d.dozuki.com/Wiki/Gcode#Section_M584_Set_drive_mapping. Also, it probably won't make any difference but M667 is deprecated and you should really be using M669 instead of M667.

fma

Ok, thanks. I applied all these corrections, but I still have the issue.

I tried to removed the U axis: not better.

deckingman

@fma Then I guess what's needed is some way of reproducing the problem - it's always difficult to diagnose when there is an element of "randomness" involved.

Unfortunately, I'm unable to help much more because I can't home my printer at all. Some of my end stops are on expansion boards and RRF 3 firmware doesn't yet work for homing with end stops on expansion boards.

M208 X-60:302 Y-100:305 Z0:320 U-1000:1000

I would propose as reason:
M208 X-60:302 Y-100:305 Z0:320 U-1000:1000
means X maximum distance is 362, Y is 405, but you home only 325 each in
G1 X325 Y325 F1800 H1
, so depending on your current position you reach one of the endstops or not, assumed, 0 position is not defined after turning the printer on. I would change to
G1 X500 Y500 F1800 H1
and the followong two also to be sure they reach the endstops..

If G1 X325 Y325 F1800 H1 reaches X immediately, M208 defines X/Y position as 302/305, but in reality Y may be at -100. So it will not reach the endstop with the following Y move, even when the first line reached an endstop. So better 500 for the following two lines also.

fma

The min values are wrong; I didn't noticed it because I home on max values. Anyway, total travel for X and Y is < 325mm, so the endstops are always reached (I'm using relative positionning). And in my tests, I'm close to the max positions, so carriage travels only a few mm before hitting the endstops.

And it was working fine with 2.02/2.03 firmwares; I just changed the S param to H param in the G1 moves.

fma

I confirm it is totally random.

Say I'm on the max position, both endstops X/Y activated. If I hit the homing button several times, I can see the machine homing X then fail, or Y, the fail, or none, or successfully home all axis.

But I find a workaround: I changed

G1 X-5 Y-5 F6000       ; move away from the endstops

to

G1 X-5 Y-5 F6000 H2    ; move away from the endstops

and it now works fine. If it can helps to find the problem...

Danal

This may or may not be related, I didn't completely follow all above... if it helps:

I have noticed that RepRap 3 on Duet 3 hardware gets "stuck" if the endstop is already triggered (physically) when a G28 is issued. Stuck meaning it won't successfully show as homed, and therefore won't G0/G1 (to move off the switch). Just won't move at all.

I've had to either manually back it off (forcing the steppers) or add something like an M564 (to allow unhomed movement) and a G0 back off of a millimeter or two (and then turn M564 back to normal), or similar, to my home... files. Of course, this back off would be problematic if the axis happened to be a physical max when the home... file was invoked.

Anyway, one of those two things is required to get that axis to move again. Not even a reboot will help.

fma

I though it was the case here, but even when I was not on the endstops, the problem occured (again, not all the time). And I was able to successfully homed even when starting from endstops position.

With the H2 param added on the mov away, it works all the time.

Interesting. Mine fails every time when already triggered.
