New experimental firmware 0.78t-dc42

New experimental firmware 0.78t-dc42 I've just released this at https://github.com/dc42/RepRapFirmware/tree/dev/Release (follow the link to 0.78t and then use the Raw button to download). Changes in this release: [quote] * Nozzle offset setting using G10 is now fully implemented * Gcode files generated by Simplify3D are now recognised when searching for file info for use by the web interface (thanks zpl) * Bug fix: Z-homing or bed probing when axis compensation was enabled caused the X and Y axis origins to shift every time you did it. * Bug fix: M92 command would only set extruder steps/mm if either 1 or 5 colon-separated extruder steps/mm values were provided * SD Image directory updated to latest web interface * When drives are disabled (due to executing the M0 or M1 command), the axes are now flagged as not homed * The movement commands that were previously in the tree1.g and tfree2.g files have been moved to the tpre1.g and tpre2.g files, to work better when G10 nozzle offsets are used [/quote] The full list of differences from RRP 0.78c firmware can be found at https://github.com/dc42/RepRapFirmware/blob/dev/Changes%20in%20dc42%20fork.txt. Things to be aware of when upgrading to this version: 1. If you have a single-nozzle machine, don't use the tpre1.g or tpost1.g files in the SD image in my repository, use empty ones instead (or comment out the commands in them). 2. If you are upgrading from RRP 0.78 (but not 0.78a or 0.78b), you need to reverse the X motor connector on the Duet board (so that the order of the colours is the same as for the other motors). 3. You don't need to change your config.g file if you already have one that works with 0.78 series firmware. 4. You can use either the RRP homing files or mine. The difference is that the RRP ones used G92 commands in the homing files to define where the endstops are, whereas mine use the axis limits set by the M208 commands in config.g. However, my homing files won't work for the Y axis on an Ormerod 2. This is because the Duet firmware (both RRP's and mine) assume that the Y enstop is a high endstop, whereas on the Ormerod 2 it is actually a low endstop. 5. The compatible web interface is version [s]1.03[/s] 1.02, which you can get either from the SD Image directory or from https://github.com/dc42/OrmerodWebControl. https://reprap.org/forum/read.php?340,412260,412260#msg-412260 Mon, 10 Aug 2026 16:33:58 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?340,412260,424275#msg-424275 Re: New experimental firmware 0.78t-dc42 https://reprap.org/forum/read.php?340,412260,424275#msg-424275 chrishamm Ormerod Sat, 25 Oct 2014 14:35:12 -0400 https://reprap.org/forum/read.php?340,412260,424263#msg-424263 Re: New experimental firmware 0.78t-dc42 https://reprap.org/forum/read.php?340,412260,424263#msg-424263

Also I noticed there is a setting in Slic3r to compensate for this by adding to the initial feed length after a retraction.

It's not only the play in the tongue. Its the Bowden cable itself that is slightly bigger than the filament. So there is an outer and inner radius the filament can take whether it is extruding or retracting. Also the Bowden tube may stretch a little when the filament is under pressure. This all leads to some dead time before the filament is fed into the hotend.

That is more or less what I am aiming to compensate for - the effective elasticity of the filament in the Bowden tube.]]> dc42 Ormerod Wed, 01 Oct 2014 17:23:14 -0400 https://reprap.org/forum/read.php?340,412260,414337#msg-414337 Re: New experimental firmware 0.78t-dc42 https://reprap.org/forum/read.php?340,412260,414337#msg-414337 DasBasti Ormerod Wed, 01 Oct 2014 16:49:39 -0400 https://reprap.org/forum/read.php?340,412260,414324#msg-414324 Re: New experimental firmware 0.78t-dc42 https://reprap.org/forum/read.php?340,412260,414324#msg-414324

Does the fact that there is between 1 and 2 mm of travel where the bowden cable meets the extruder make any difference or is that taken care of with retraction.

Do you mean play where the Bowden cable meets the extruder drive? I don't have any play there, provided that I have the tongue inserted properly.

Yes I have tried two reprinted tongues and I always have had play at this point,so I thought it was normal. I will retry reprinting this with a mind to making it fit better.
Thanks]]> jondel Ormerod Wed, 01 Oct 2014 16:07:29 -0400 https://reprap.org/forum/read.php?340,412260,414315#msg-414315 Re: New experimental firmware 0.78t-dc42 https://reprap.org/forum/read.php?340,412260,414315#msg-414315

No, any play in the end fixing of the Bowden is, as you say, taken up by the retraction - the Bowden will be hard against the stops all the time it is extruding.

Dave, thanks for the feedback! I'm glad it's working well for you.

My next planned firmware changes are:

1. Complete the serial interface support, ready for the TFT controller board.

2. Rewrite parts of the Move code to provide smoother movement, to provide adjustable pre-compensation for Bowden extruder lag, and to support delta printers. This probably won't happen until November.

I await the Bowden lag modification eagerly, I'm hoping that it will make a huge difference (but I may well be overly optimistic).

Dave

will a bowden lag modification reduce oozing? or better starts of new perimeters?

Not oozing so much as blobbing. That's the theory anyway, we won't know until we try it. The theory is that there is a time-lag between the extruder motor changing speed and the resultant change to the plastic flow at the nozzle. This results in insufficient plastic flow at the start of a move, and too much at the end (blobbing). So the idea is to modify the firmware so that the extruder motor moves are sent a short time ahead of the XY moves (or the XY moves are delayed, which amounts to the same thing). The hope is that it will result in the plastic flow at the nozzle becoming more in sync to the XY moves and so plastic will be deposited more accurately at the place it is needed instead of the place it had been needed a short while ago.

This is probably a dome Question, but i am Cur-ease. When i send the command 'M906 E800', and i have the expansion board. Dos it also set the current for the other fore Drive motors on the expansion board ?

Yes it does. To set them individually, use e,g, 'M906 E800:1000:900'. However, I've just checked the code and it has the same bug/feature that the M92 command has, so for now you would need to provide 5 colon-separated values. This will be fixed in my next build.]]> dc42 Ormerod Mon, 29 Sep 2014 06:59:44 -0400 https://reprap.org/forum/read.php?340,412260,413083#msg-413083 Re: New experimental firmware 0.78t-dc42 https://reprap.org/forum/read.php?340,412260,413083#msg-413083 DasBasti Ormerod Mon, 29 Sep 2014 01:47:37 -0400 https://reprap.org/forum/read.php?340,412260,413016#msg-413016 Re: New experimental firmware 0.78t-dc42 https://reprap.org/forum/read.php?340,412260,413016#msg-413016 gdwinslow Ormerod Sun, 28 Sep 2014 17:46:18 -0400 https://reprap.org/forum/read.php?340,412260,413013#msg-413013 Re: New experimental firmware 0.78t-dc42 https://reprap.org/forum/read.php?340,412260,413013#msg-413013 gdwinslow Ormerod Sun, 28 Sep 2014 17:42:44 -0400 https://reprap.org/forum/read.php?340,412260,412448#msg-412448 Re: New experimental firmware 0.78t-dc42 https://reprap.org/forum/read.php?340,412260,412448#msg-412448
The shifting of X and Y axes did not happen this time. So fingers crossed.

EDIT: Just had the test print fail because the Y-axis did not move at all. I does move at first to home itself and than fail to do any movement at all during the print. even running something like circle.g does the homing ok, moves the X-axis ok but the Y axis not at all.

Looks like there is a problem with the steps per mm for the x axis since the square does move correct in the X-axis and not correct in Y-axis

EDIT2: looks like the Y-axis thing is my fault for having M208 X210 Y28 instead of M208 X210 Y208 in my config.g]]> DasBasti Ormerod Sat, 27 Sep 2014 07:32:57 -0400 https://reprap.org/forum/read.php?340,412260,412446#msg-412446 Re: New experimental firmware 0.78t-dc42 https://reprap.org/forum/read.php?340,412260,412446#msg-412446 dc42 Ormerod Sat, 27 Sep 2014 07:26:17 -0400 https://reprap.org/forum/read.php?340,412260,412443#msg-412443 Re: New experimental firmware 0.78t-dc42 https://reprap.org/forum/read.php?340,412260,412443#msg-412443 MrCrispi Ormerod Sat, 27 Sep 2014 07:20:09 -0400 https://reprap.org/forum/read.php?340,412260,412409#msg-412409 Re: New experimental firmware 0.78t-dc42 https://reprap.org/forum/read.php?340,412260,412409#msg-412409 dc42 Ormerod Sat, 27 Sep 2014 03:11:13 -0400 https://reprap.org/forum/read.php?340,412260,412374#msg-412374 Re: New experimental firmware 0.78t-dc42 https://reprap.org/forum/read.php?340,412260,412374#msg-412374

* Bug fix: M92 command would only set extruder steps/mm if either 1 or 5 extruder steps/mm was provided

Could you elaborate a bit on this? Would the command only work if the value provided was 1 or 5? The Ormerod extruder drive normally has a value over 400, would that command then just never have had any effect earlier?

Awesome job as usual!]]> jstck Ormerod Fri, 26 Sep 2014 20:11:43 -0400
