Beta of latest Marlin_V1 w/ Solidoodle Patches (Oct-13) (All Boards) (Page 4 of 4)

Ehm... What exactly? Isn't it the way it works now? You can already set the first layer height in Slic3r.

I thought you had to set the first layer in the slicer so it would know how far above the bed the nozzle sits when it is homed?

I don't know if the slicer is bright enough to deal with that value being set to zero (might be interesting to try it).

It would certainly make more sense to me to set the home position to being directly on the print bed then let the software decide how much to raise the nozzle off the bed for the 1st layer. A lot less screwing around with shims and such (assuming you can get the bed level detection to work using the nozzle itself).

No, the first layer height actually corresponds to a move in the Z direction to that height. You will see it around line 10 of your gcode (G1 Z0.3)

This is the idea: you are using a 0.1mm sheet of paper for the calibration because when the nozzle heats up it becomes slightly longer and it will almost touch the bed.

I'm flat out this morning, but in brief:

1) Thermistor settings are updated to reflect what Solidoodle have in THEIR firmware from June. This also includes their altered acceleration settings. I commented on it back on the first post and outlined some of the changes.  I did the updates to lawsys firmware back in May last, and in May, they still had 6.

Regarding the tables themselves - they are the same Marlin tables as used by the entire rest of the reprap community pretty much...

As for the Bed temp - Yes forget the IR thermometer for measurement. Did you also enable BEDPID and if you have, have you tuned it using the M303 E-1 S90 C8 command and pasted the updated values back into the BEDPID stuff ? If you really want - simply change the thermistor setting back to 6 - Its an inferior table that even admits that in the firmware.. *shrug*

Finally - the Nozzle temp is entirely unrelated to the motherboard. It is a factor of where Solidoodle place their Thermistors on the nozzle. Yes your temp limits still apply as its still effectively 'real temp - 25-35°'.

All 10 bit ADCs

Sure, I will follow that thread.
I reverted back to table 6 for both thermistors because I have the impression the layers are more fragile when the extruder is run with the table 1, all other settings equal, therefore I think the table 1 is making temperatures lower than expected.
I definitely need a thermocouple of something else...

By the way, I let you know if the new FW has improved comms... because I was getting "last line is not line number..." error sometimes.

Its coming still - was waiting for a security audit to finish and had to clean a few things up functionality wise. Should be out this weekend - unfortunately the 'silly season' is well and truly upon me with work so not had much time at all to focus on it past week.

Hi Adrian    my name is Bill   I am begging for your  Help. I got get my SD3 and Panelulo 2 to work
My SD3 came Dec 24Th 2013 my Panelolu in March 2014  I have tried all suggestions from the forum and every Version of Marlin and Arduino they have recommended and each comb gives me a different set of error codes  I an not a programmer  Could you please tell me step by step from start to finish what I need to do to make this work . I know I am asking a lot  Please help me  My email address is    [email protected]   or [email protected]   Thank you for your time
PS  the Mother Board  says   Solidoodle   REV 3

Thank you tealvince I am leaving for a trip But I will get back to it next week. Basically I need to know how to get Panelolu2 ( from Think3D Print 3d) to work with  my SD3   (Solidoodle Mother board Rev 3 ).What IDE to use (version and link ) What firmware (Marlin version ?) and what steps in what order I need to do . I have a basic set of computing skills but I am not a programmer. I have tried so many suggestions that I am totally confused. I can"t imagine that I am the only person to ever try to connect a Panelolu 2 to a Solidoodle 3 Rev 3. I think I need to start from scratch and am looking for help in doing that .   Thank you for taking time to talk to me      Bill D.
