Safety...
I have more or less the same problem.
No matter wich PID setting i get & write into the ROM, I get a steady temperature that is 0.6 °C below the setpoint.
Therefore sometimes it takes ages to start a job.
It happens both at PLA and ABS temperatures.
I would greatly prefer having constantly 0.6 °C above the setpoint :-)
Any indication (other than increasing DRIVE_MAX ?)

IMHO, you could put everything related to each extruder to a single graph area, on each graph you have setup, actual readout, power output.
I believe that the Y axis autoscaling is working great, therefore having graph area that are way "lower" than actual could let you fit up to four extruder on one page, keeping the manual commands button untouched.
IMHO, as usual.

As I am starting to play with twin extruders, I've stepped into some things that could be improved (in an already great package).
Host:
1) Temperature graph with both extruders shown at the same time
2) Possibility to show both extruder settings at the same time (but I am not sure there is enough request for this)
Firmware:
It works! Nothing to say :-)

...It was actually a BAD BATCH of thermocouples.
Changing to a new supplier has fixed (crossing fingers) this issue.
Still, I don't understand why Marlin is behaving better (flickering was less noticeable, perhaps sort of filtering somewhere ?).

Perhaps I am not being clear.
What I am trying to tell you is that the temperature reading is flickering.
The LCD temperature display is changing every second and the fluctuation is +/5..10 degrees °C.
Nothing to do with power output, that is working OK, and the PID logic is OK.
Heater is behaving correctly, but if the reading is flickering even setting a good PID is not easy, as the variance

Sir, M303 was tried many times, and having got no result I investigated a bit more, that's the reason of my request: the flickering is there even when extruder is turned off and machine is cooling, getting same flickering values (if heating is OFF should be no PID activity, isn't it ?).
It seems that the value that repetier fw is reading is subject to some "noise" somewhere along the conversion

I've been monitoring the temperature reading of the thermocouple on the extruder, and on the same hardware, same extruder, same everything but different firmware (marlin) I get different temperature "steadiness".
With marlin, the temperature flikers +/- 1.5 °C at 210 °C, while with Repetier the flickering is +/- 5/10 °C at the same temperature.
Can't be PID setting, as the flickering period is

As usual, maybe I am missing something, but it seems to me that OPS speed is proportional to current printing speed.
IMHO the retraction speed should be as fast as possible, regardless of printing speed.
I believe that fixing OPS it could be one of the biggest pluses for Repetier firmware.

Out of curiosity, do you get decimal values when reading from thermocouple ?
I switched from Megatronics 1.0 to 2.0 and yet I get just integer readings ( 201.0 °C then 202.0 °C, when T is increasing).
I never had a fractional value (i.e.: 201.4 °C) since I am using Repetier firmware.
Am I missing something ?

1) All I can tell you, is that I simply set the Configuration>Printer setting>Printer setting tab>Number of extruders to zero. After quitting the program, there was no way to start it again. Regediting the number of extruders back to "1" allowed me to restart program.
2) Firmware is already set as
#define HEATED_BED_HEATER_PIN HEATER_2_PIN

Found two problems:
1) It is possible to config "zero extruders", but software then locks up and dosen't run anymore. Solved changing (regedit) register value.
2) On a multiple extruder board (Megatronics 2.0) when turning on the heated bed, it turn on also the HEATER_1_PIN
Especially issue #1 is locking me...

Why the pin numers are hardwired inside UICONFIG.H ?
I mean:
#define UI_DISPLAY_RS_PIN _BV(4)
#define UI_DISPLAY_RW_PIN _BV(5)
#define UI_DISPLAY_ENABLE_PIN _BV(6)
#define UI_DISPLAY_D0_PIN _BV(0)

What do you mean about burning drivers ?
On this link the stepsticks are depicted with the trimmer on the right, therefore I assume that this is the right position.
Recap: facing the board with USB toward you/bottom, the stepsticks should be mounted with trimmer facing right side.
There is the PCB drawing available, depicting the motor output traces on the top of each stepstick (stepper dri

Found critical values, set to outlandish values. No way.
Disabled Heated Bed. No way.
I don't know why and when, but now I get an "external reset" each time I start the thing.
Tried also outlandish value in accel and speed. No way.
Back to Marlin, but waiting for news here: I love Repetier.

Disable Ops. No change.
As soon as system is started, the extruder is humming (no motion asked from host).
Tried any speed. No change.
As soon as I start host I get "printer in dry mode".

Wait a second.
From above thread, it seems that Pololu driver works in other sockets and stepper, too: both should be alive and kicking.
Therefore either the motherboard pololu socket/motor connector are defective OR the software setting are just wrong.
Try to set the accelleration to half current value. See if hammering noise changes.
Funny enough, I have same problems now on my Megatronics bo

Update...
It turns out that with a 100uFarad condenser ( parallel wiring ) the thermocouple should work as expected.... and it works!
Now the output is steady, and reliable.
Therefore IF you have a thermocouple AND you have a Megatronics 1.0, do yourself a favor and buy a couple condensers...

Update:
K thermcouple arrived, but results aren' too different.
Temperature reading is erratical.
If thermocouple shielding/tip are in contact with metal frame, readout is skyrocketing.
If kept away (insulated) from grounding, it works...until stepper aren't engaged... then readout is going down.
Checked PSU (brand new, server grade): no problem.

Dave,
What about extruder stepper settings ?
For instance, did you double check the steps/mm for E0 ?
Accelleration ?

Found the problem.
Was using a "J" thermocouple... when I was convinced it was a "K".
As soon as I plug in a TRUE "K" (as expected for Megatronics) will report.

Thank you, Brupje !
Hope your work will be backward-compatible with Megatronics 1.0 (but I hope to be able to order you soon several 2.0 boards) :-)
ANYWAY: I won't be upset if in the meantime someone tells me HOW to make thermocouple work with Repetier firmaware.

Some progress.
1) Be sure to set EEPROM_MODE to 0 during testing :-)
2) LCD setting in PINS.H are not considered. Need to insert them into uiconfig.h
3) Encoder settings, too, need to be changed directly in uiconfig.h.
4) Thermocouple still dead (working in Marlin)
My humble suggestion: why not keep the Marlin approach: just set PINS.H then set the options and compiler takes care for subsi

Tried new mod file from above and/or github. Still no luck with thermcouple (or LCD).
The only good thing so far is the SD working, while with Marlin it doesn't :-)
Any idea ?

I would like to point out that many CE marked goods coming from China are NOT the real CE, rather a sneaky China Export marking. Therefore, unless you are using a PSU from a well known producer, it's a safe idea to use a fuse (as Nophead wisely suggests) before seeing some burning issues :-)
