Duet3D 1HCL - Closed Loop Controller Beta test

supertb1

@lirwin17 I just reinstalled the latest firmware and it is still reporting no to close loop enable at power up

supertb1

@lirwin17 I tried rolling back the 1HCL board firmware to the previous one, still showing no on the enabled... and it won't let me do any of the tuning variables

supertb1

@t3p3tony I tried to change the closed loop back to open loop on the card in question and taking the "C" value out of " M569.1 P50.0 S1 T2 C20 E20 R100 I0 D0 ; Configure the 1HCL board at CAN address 50 with a quadrature encoder on the motor shaft that has 20 steps per motor full step.
M569.1 P51.0 S1 T2 C20 E20 R100 I0 D0 ; Configure the 1HCL board at CAN address 51 with a quadrature encoder on the motor shaft that has 20 steps per motor full step. and now with the encoded motor it will not operate in open mode either... I reinstalled the 3+1 firmware and put everything back the way it was....

supertb1

@lirwin17 Just for my information, when you say Power up (so config.g runs) you mean simply energizing the boards correct... or is there another command I need to enter to get the "config.g" to run?

supertb1

@supertb1 so after I did this using just the config it dawned on me that I probably would have to disconnect the encoder from the 1HCL board as well... you guys did a great job on these boards... very smart...lol

supertb1

@lirwin17 I'm not trying to be extra special here... I guess I need to start from the start... how do I trouble shoot this issue I am having?

@supertb1

I think you are using M569.5 instead of M569.6

What does sending

M569.6 P50.0 V31

Result in?

Hmm you should never need to disconnect the encoder from the board unless you want to - the board should work in open-loop mode without anything needing to be disconnected, and you shouldn't need to disconnect it to cycle power or anything.

That yes to the closed loop enable was there before I updated the 1HCL board to the latest firmware and now at power up it reports "no" to the close loop enable

Righty I'm just looking over your config.g, it's been posted a few times, so let me just re-post here so that we're all looking at the same thing:

G4 S3 ;wait for expansion boards to start

M84 S30 ; Set idle timeout
M917 X0 Y0 ; Set the closed loop axes to have a holding current of zero

The first thing that jumps out is line 5:

M569 P51.0 D2 S1 ; Configure the motor on the 1HCL at can address 51 as being in closed-loop drive mode (D4), Open loop (D2) and not reversed (S1) Y axis

Your comment says it's closed loop, but the actual command is using D2, which is an open loop mode.
However, your line above using P50.0 is correct, and that seems to be the driver you have been using, so I assume you are aware of this and this is all fine.

It might be worth only having one closed loop board plugged in at a time whilst we're diagnosing this issue. Just to rule out issues like them accidentally sharing a CAN address or something like that.

I suspect the problem here is line 2:

M569.1 P50.0 S1 T2 C20 E20 R100 I0 D0

This might be our fault - that particular command has gone through a number of changes, and it should have been updated in all the docs - except we seem to have missed this section! So if you've copy-pasted from that, this may be where our issues are coming from - I'll update that page now.
The GCODE dictionary page for M569.1 is definitely correct though, so I'll re-write your M569.1 command from first principles:

Your motor driver is 50.0 - so P50.0
Your encoder is a quadrature on motor shaft - so T2
From googling your motor serial number, you have this motor? That page gives a 'resolution' of 1000. No units though, how helpful. I'll assume that's CPR. That motor is also 200 step/rev, so we do 1000 ÷ 200 = 5 - so C5
Sensible error thresholds are maybe 5 & 10 - so E5:10
We'll leave R,I,D as default so you don't need to include them for now

Putting that all together:

M569.1 P50.0 T2 C5 E5:10

I suspect when your config.g file was running, it was erroring at your M569.1 command - so never getting to M569 to turn the 'no' to 'yes' in M122.

It might be worth running M98 P"config.g" manually and seeing if any errors come back. Then, change your M569.1 command for my M569.1 command, run M98 P"config.g" and hopefully no errors will come back.
Once that's done, turn it off and on again, and you should be good to go

Edit: I got my .5 and .6s confused I've corrected them now

Yes, Tony is also right here:

I think you are using M569.5 instead of M569.6
What does sending
M569.6 P50.0 V31
Result in?

The M569.5 command is for recording. This does let you pass in a manoeuvre (V parameter) to do. So running M569.5 as you describe would technically work to do a tuning move...
However, you'll also be making a recording each time, so you'll quickly fill up your SD card with recordings. For this reason, unless you intend to do a recording, using M569.6 is preferable to do a tuning move.

For anyone curious as to why there are 2 GCODE commands to do tuning moves, the rationale is that with HTTP delays etc, it is unlikely that you'd be able to send M569.5 and M569.6 quickly enough to record a tuning move. For that reason, M569.5 allows you to specify a tuning move that gets started just before the recording is started.

@supertb1 I have P51.0 disconnected at the moment as advised

MaxGyver

Short update:

I am on my third print with the closed loop drivers and so far they are working quite well. The axes are sticking to their position very well. I really have to apply a lot of force to push them off course, and they will snap right back.

I am printing with up to 300mm/s and was able to increase my acceleration and jerk significantly. On the downside I had to limit my max. speeds to 20000mm/min or 300mm/s.

@lirwin17 I have two motors on my Y axis. They are both wired to one 1HCL board, but only one has an encoder. It calibrates fine, and I did not spot a significant problem during printing. Only the recorded graphs were of no use on this axis (at least for me). Maybe something to keep in mind for future development.(especially for autotuning. )

Furthermore, I have the impression that the drivers run in full step without any microstepping as soon as I switch to closed loop. It sounds very much like my very first printer. The prints also show a strong stepping pattern.

Cheers Max

@lirwin17
since the change on the M569.1 line to P50.0 T2 C5 E5:10
I am now getting closed loop enabled : yes
on P50 V8 it is saying that the drive has an incorrect polarity
V32 made the drive run off to the end of it's travel
M569.6 P50.0 V64
Warning: No new tuning errors have been found, but some existing tuning errors exist. The drive has not been zeroed. The drive has not had it's polarity checked. The drive has not had it's control checked. The encoder has not had it's count per revolution and V128 is the same result
