On a Bowden extruder, that will make it more important to use the correct pressure advance setting.

It's not a Bowden extruder, it's a flex3drive.

A Flex3drive might require pressure advance to compensate for the torsional elasticity of the Bowden cable. I've never used one, so I don't know whether this is the case or not.

I don't use pressure advance on my flex3drive and the corners are way sharper than any bowden I've used. I think the high gear ratio takes care of that.

Apologies for the off-topic question but what speed, accel, jerk are you using with the flex3drive? I am using 25, 400 and 10 with no pressure advance and normally get good results.

Too bad that M703 does not already work with filament loading.

Thus, no change to the filament load macro would be necessary!

Doesn't it, in firmware 2.02beta1?

When filament loading it does not work (no temperature is set, no error messages)
My guess is that the filament name is updated only after the load, so M703 has no macro name.

When unloading it works!

Have you read https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD#Section_M703_Configure_filament to see how M703 is intended to be used?

XY Speed: 80 mm/s
XY Accel: 1000 mm/s^2
XY Jerk: 800 mm/min

E Accel: 125 mm/^s
E Jerk: 120 mm/min

No pressure advance

I haven't even attempted to do any advanced tuning let alone tried to tune out the ringing yet but the corners are pretty sharp.

Thanks for the numbers. Interesting, very different from what I am using. For the extruder, I am using higher acceleration and much smaller jerk (currently 1000 and 10 , respectively) and get good results. Until recently I have been using 400 for the accel and have upped it to 1000 now as it still behaves OK. 3000 was too much as it wasn't retracting at all using that. I shall try increasing the jerk now.

burtoogle

I upped the extruder jerk to 100 and it's printing fine along with extruder acceleration of 1000.

Back to testing M593. The results I am seeing are still very much like the picture I posted earlier in the thread in that some ringing that was occurring after a relatively shallow hole was pretty much getting removed but ringing that occurred downstream of a longer edge wasn't being reduced (or maybe just a little, hard to tell).

Another oddity is that when I print that little 20mm widget that has X and Y and dots on the other sides. I get more ringing downstream of the X / Y / dots in the upper half of the print than the lower half and the upper half of the model has rounded corners and the lower half has sharp corners! When not using M593, the amount of ringing downstream of the X / Y / dots is similar for both the top and the bottom of the print. Don't understand that at all.

Were there any changes in the compiling process? I brought these files into Eclipse, but when I go to compile I get about 30 errors coming from "WiFiInterface.h". Most are of the form "symbol/type xxxxx cannot be resolved." I also get this error: make: *** [Duet2CombinedFirmware.elf] Error 1.

I have make.exe and MessageFormats.h in a folder included in the path, and I can confirm that they are listed in the includes folder of the project. Is that still the correct process?

Thanks for trying this out. It sounds like I still have a little more work to do on this feature.

@gizmotronx5000 You might have to update to the latest MessageFormats.h from DuetWifiSocketServer dev branch. I had the same issues until I did that. No issues since then anymore.

GizmotronX5000

I thought it might have something to do with that, but I just grabbed the most recent version and tried again. No luck. It looks like I probably had the most recent version already, since it was last updated in March 2018. I added it to my includes. However, I see if I open WiFiInterface.h there is a warning saying "Unresolved inclusion MessageFormats.h". I must not be including it properly or maybe there is some sort of conflict?

wilriker

@gizmotronx5000 Did you include it as a workspace path or as an absolute filesystem path in eclipse? I did the latter and explicitly have DuetWifiSocketServer not in my workspace at all.

GizmotronX5000

It's an absolute file system path not included in my workspace. I don't have the duetwifisocketserver project, just the messageformats.h, which worked before.

wilriker

@gizmotronx5000 I'm sorry, but now I run out of ideas.

it would help if you post the exact error messages.
