Printrboard Firmware - testing

[Michael@Oz]

Results - for Printrbot Original

Loaded Marlin-unified-v1.hex - OK

Pronterface
Connected - OK
M503 - OK results match configuration.h (not my settings)
Set hotend temp - OK
Set bed temp - OK
(monitoring g-codes working, temps rising)
X axis home - OK
X axis move - OK
Y axis home - fail, no movement
Y axis move - fail, ditto, either direction (and PC/printboard interface slow/stuffed - need reset/disconnect/connect)
Z axis home - fail, no movement
Z axis move - fail, as above
Extrude - OK
Manual Fan on/off (ie M106/7) - OK
M119 check endstops on/off - OK

Let me know if you want anything else tried.

If my recollection is right, that the Jr has a slightly different config, if there are spare pins post LCD/extra extruders etc, you could always bridge a pin (+ or gnd) to use as a 'config selector' so you could have one unified firmware.

[lwalkera]

The only difference for the Jr is one of the axis are reversed, and different soft endstops.

[Michael@Oz]

So for Silverfingers & others with a Jr, the firmware you're testing here is just (for now) for the Orig/LC/Plus (maybe Simple)? Or have you found a way to unify the Jr too?

[Michael@Oz]

Note for his Jr, changed the stepper wiring to use the newer firmware.

For V1 Plus, using the "Unified" Plus+ firmware, I have discovered my bed temperature is more accurate. Is there new thermistor mapping for the bed temp? My indicated temp used to underreport by a linear 20 C. For example, I would set 62 and measure 82. Now it is within 1 C of what I set.

I have also had to make a minor change to my extruder calibration. It seems to be overextruding by a few percent. My Z axis is also faster. All other axes and behaviors seem unchanged so far.

p.s. M115 spits out the default Marlin mendel string from language.h
#define MACHINE_NAME "Mendel"
#define FIRMWARE_URL "http://www.mendel-parts.com"

You could think of making it Printrboard specific. ??

SD card printing printed OK, but had a spurious message at the end, could have been USB cable issue as I had a few pronterface comms errors of late.

I then got a funny at the end of a non-SD print. I then added a M114 to my end g-code string to get a known msg.
Also got a funny end of next print (I copied the msg, but don't have it at hand just now), with the M114 imbeded in the echo, so something is weird.

I'll replace the cable and try again tomorrow, but this wasn't happening yesterday before the F/W.

I'll also revert F/W to test, then re-do the new unified v2 again.

This is after it homes X at end of print, so printing seems normal...

(I changed nothing on the controlling PC)

redid SD card print OK. Msg at end is normal
#define SD_FINISHED_RELEASECOMMAND "M84 X Y Z E"

Fixed end g-code and got a proper print finished msg from pronterface, ie print ended at... and took...

But another print did not, printer homed-x at end of printing but pronterface did not output msgs, but I reverted to previous F/W and it did the same, so I have some issue...

I've now done a few prints and they seem normal.

One observation, the polled temp msg (M105 I presume) has e-temp b-temp then @:127 B @:127 [max while heating up] (Unified v2 F/W), while Limitsave v4 F/W goes to 128 and does heat up slightly quicker.

Thanks Laine! V2 is running fine on my Plus with Rev. D Printrboard. I am very grateful!

It's working on my Jr. I reversed the Y calibration.

One problem. Y-axis homing is messed up. I appear to try to go in the positive direction. Is there a known fix for this (other than reversing my Y motor wiring and go back to positive calibration)?

Thanks to everyone who made it possible for me to extend my PRJR z-axis! That's a big deal to me.

Thanks to lwalkera, Michael@Oz for contacting him about it in the first place, RetireeJay for help with the y-axis reversal. Did I miss anyone?
