RepRapFirmware 3.2 planned improvements

Bipotronic

Implementation of Variables of GCode Meta Comments would be useful. Or is this function already implemented?

Do you mean the M73 command?

Yes, M73. This is what I got from in a 22minutes (estimated) gcode file:

M73 P0 R22
M73 P0 R22
M73 P4 R21
M73 P9 R20
M73 P13 R19
M73 P18 R18
M73 P22 R17
M73 P27 R16
M73 P31 R15
M73 P36 R14
M73 P40 R13
M73 P45 R12
M73 P49 R11
M73 P54 R10
M73 P58 R9
M73 P63 R8
M73 P67 R7
M73 P72 R6
M73 P76 R5
M73 P81 R4
M73 P85 R3
M73 P90 R2
M73 P94 R1
M73 P99 R0
M73 P100 R0

In the early phases of the print probably the remaining time R is more useful for the estimation and in later phase probably the percentage P and actual time so far will give a better estimation.

The markers seem to be in (estimated) 1 minute intervals.

I've added M73 to the list for consideration.

Thanks.

It's on the list for implementation, but IMO it's pointless as long as jerk or junction deviation is needed at corners. The first-order motion components need to be made continuous before or at the same time as worrying about third and high order components.

What is causing that dependance?

zapta

@dc42, FYI, I run a small experiment correlating the M73 markers with actual prints (replaced them with G10 and M140 that propagated the values to standby fields in the json). Results look very good, both for linearity and absolute time values.

My slicer has default setting, without any calibration for the max speed, acceleration and jerk of my printer.

You can probably run tests much faster using simulator mode.

Please add inverted M80/M81 for meanwell PSUs.
I know. I'm inpatient. Is it a lot of work to implement this?

SpoonUnit

Could the option be added to set the min limit for behaviours similar to that controlled my M190. A default of 41 seems fine, but ultimately arbitrary, and having the option to hand control of this value to the operator would be nice. M143 sets max limits, perhaps it could be overloaded to support specifying min limits also?

@dc42 really looking forward to playing with G5 Bezier curves!

This is included in the planned work to make the PS_ON pin configurable.

Support G5

Does this involve maybe also G15 / G16 ? (I don't know if any slicer know how to use them, I only used them when I wrote code manually on my old milling machine)

Maybe I'm just more confused than normal but I don't understand the versioning system.
Is 3.1.0, soon to be 3.1.1, not the latest stable release? If so, why is the next version going to be 3.02?

A Former User

@DaveA understandable confusion; the current 3.1.0 was supposed to be 3.01 until about the day it was released, presumably what would be 3.02 will be 3.2.0.

The next stable release, not counting patch releases such as 3.1.1, will now be called be 3.2.0. I have changed the title of this thread.

I'm hoping requests for 3.2 will also be entertained: Extend M409 to allow multiple keys to be requested.

For example, assume something embedded that wants to determine how much time is probably left in a print (using the simulated time) would need to request job.file.simulatedTime as well as job.duration. Having to request the entire 'job' key to 3 levels deep can result in a large buffer. Having to make 2 M409 requests doubles the time needed to get the information.

On the other hand, if M409 supported multiple keys, the request and response could be simplified:

M409 K"job.duration","job.file.simulatedTime"

(For discussion, I've also started a new thread: https://forum.duet3d.com/topic/16450/m409-multiple-keys-at-once)

Regarding line item 48: According to Marlin docs, UBL does support loading an existing mesh and applying 3-point or grid based tilt adjustment.

Is the spreadsheet in the first post still being maintained?
Does the equivalent exist for 3.3?

Many of the items that were planned for 3.2 have been deferred to 3.3. You can see what's implemented in 3.2 in the RRF3 whatsnew file.

why the continual push back ?

dc42

It's hardly a continual push back. The 3.2 release includes nearly 40 improvements, not counting bug fixes.
