RepRapFirmware 2.02RC7 available

Mugga

Hey guys,
today I updated to 2.02RC7 coming from 2.01. After the update I cant get my bed compensation working. Normally I would have done a G32 and from time to time G29 which I'm loading in gcode with G29 S1 before a print. This worked for me.

But now after a G32 I'm getting the message:
Warning: 3/4/5-point bed compensation is deprecated and will be removed in a future firmware release. Please use G29 mesh bed compensation instead.
Bed equation fits points [10.0, 10.0, 0.188] [10.0, 185.0, 0.324] [185.0, 185.0, 0.125] [185.0, 10.0, 0.246] [100.0, 100.0, 0.190]

After that I've just used G29 but the nozzle is about 1mm above the bed and z-baby stepping isnt working.
Can someone help me with that?

Never mind guys, just redid the z-probe height configuration. And its working!
But with no G32 anymore, what is the proper way for lvl a cartesian? Just from time to time a G29 and normally a G28 for all axis? Or do I have to do a G29 everytime?

Using G32 for bed compensation is still supported, but has been deprecated for some time. The suggested alternatives are:

Use mesh bed compensation in place of G32, with a 4-point mesh of you were using 3- or 4-point G32 bed compensation, or a 9-point mesh if you were using 5-point bed compensation;
Use a finer mesh spacing, but before most prints don't probe the bed, instead use G29 S1 to load the height map file generated the last time you ran mesh probing.

@mugga You can still use G32 and bed.g to do manual or automatic bed leveling with independant lead screws. The main change I think is to use the mesh grid of g29 since it's more flexible instead of the simple plane used with G32 and a few defined points.

Computiger

where I can geht the DuetWebControl 1.22.6 ?

Phaedrux

@computiger It should all be included in the unified zip file now. One download, one zip file, upload the whole zip file, and all the firmwares are updated together, including the DWC.

spunone69

It uploads fine until the very last file "dwc.js.gz" which errors out every time...

spunone69

@spunone69 Nevermind...I figured it out...but it still won't home any axes!

Any error messages? Which firmware version are you upgrading from?

@dc42 I just installed this hoping it would solve my problem but I'm still getting the problem that the my Duet Wifi doesn't seem to understand G2/G3 commands in the R Form. For example G02 X-85 Y-63 Z4. R28207. It says that its missing the parameters (likely understanding it to be missing I and/or J). Am I doing something wrong here?

dc42

Nobody has asked for the R parameter to be supported in G2/G3 before, and until I did some research after reading your post, I wasn't aware of it. I can add it to the wish list for release 2.03.

@dc42 Thank you very much.

David, thanks for all the work you've done to make Dynamic Acceleration Adjustment (M593) available. Seriously, if you're ever in the Bay Area, I'm buying the beer (or offering my homebrews).

I've spent hours and dollars making changes to my large Kossel to chase out ringing issues, as documented here:
https://groups.google.com/forum/#!topic/deltabot/d_JHfa4qFck
... changing out the frame (1515 -> 2020), carriages, effector (printed -> Smart Effector), rods, extruder style (bowden -> flying), cooling, 12v->24v, hotend, you name it.

In 10 minutes, with a single command (M593 F51.6), I have possibly the single most obvious print-quality bump I've seen in 5 years on this printer. The pic below is a 10mm double-wall multi-test cube print; the face shown is one where the head makes a long travel move to the shown left face, then moves right, for a 40 mm/s external perimeter.

The motion is not 100% gone, but it's obviously vastly reduced. I don't know if this is due to frame flex, rod flex, the weight of the extruder connected via a bowden time above, or something else. But whatever, it's really good now. Going to try out pressure advance next.

Also, I'm very excited that the WiFi continuously tries reconnecting in post-2.0.0 builds! That was the single biggest annoyance from the past. The upgrade to 2.0.2RC7 is great.

@dc42 It was 2.01, I realized I had to install 2.02 RC2 first...

@brandonh, thanks for the feedback! I'm glad it is working well for you. May I re-post your before/after image elsewhere?

Just for my curiosity and to reproduce the "exact test", I'd like to print this on my BFD (Big Fast Delta). Would you mind posting the STL and G-Code?

If you don't want to post (or don't have a good place), I am danal (dot) estes (at) gmail (dot) com

Thanks!!

My results haven't been that dramatic, but I definitely think it's made an improvement. I think it's complicated by the XY weight difference on CoreXY mainly. @dc42 is there a way it could be expended to allow more than 1 frequency to be canceled?

brandonh

@dc42 Sure, go ahead

@danal

The STL is here (not mine):

https://www.thingiverse.com/thing:1159886

I got these results with 1 or 2 perimeters and a few mm of brim to keep the boxes together, using Slic3r PE 1.41.2. I assure you there's nothing interesting in my g-code.

The only change between those two was the addition of M593 F51.6 to the config.g file and running this beforehand.

Danal

@brandonh Thanks! I'll try this on a couple of deltas with duets. Will be a little while, both in long prints right now.
