Firmware 3.0 update. Heaters problem
-
Hi,
I went to 2.04 to 3.0 firmware update.
Fixed fans problems.
Fixed z-probe homing etc.
PID auto tuned heaters, sensors no problem.The problem is I can configure heaters(H0/H1/H2) manually and can reach any temperature I want but when start of the print I am getting error something like heater1 never reaches target temp in 1.7 sec.
I see that H0 heatedbed is active and getting warmer but heater1 and heater2 never gets activated but the firmware thinks that they are active but not reaching the temp. point.
Normally at the startup of the print, first the heated bed was reaching the target than extruder activated. There should be smt. I am missing.
Thanks -
Did you PID tune the bed heater? Did you save the results?
What do you have in your start gcode for the heaters?
-
Thanks.
Yes I have pid tuned all heaters including bed. The print file is from sdcard calibration cube. I mean it is old gcode file on sdcard that i print succesful one week ago.
-
@secure Sounds like there's something at the beginning of the gcode file that is setting temperatures. Please post your config.g, config-override.g (if used) and the gcode file that is causing the problem.

@droftarts There is no problem with the gcode really. I have tried almost 5 old gcodes stored in SDCard. They were fine before and printing without problem

@secure Do you have a copy of your config.g from when you were running RRF v2.04? This may help with some of the following.
First, you need to get your temperature sensors reporting accurately.
M308 S0 P"bedtemp" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin bedtemp M308 S1 P"e0temp" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin e0temp M308 S2 P"e1temp" Y"thermistor" T100000 B4138 ; configure sensor 2 as thermistor on pin e1tempT100000 B4138 is the default thermistor setting, for a Honeywell 135-104QAD-J01 thermistor that shipped with hot ends from RepRapPro, who have been out of business for 4 years! So I doubt you have the correct thermistor settings, and likely the temperature your heaters are reporting is not accurate. All 100k ohm thermistors have a resistance of 100k ohms at 25C, and will be fairly accurate at room temperature, but they report very differently as they get hotter. So please check what thermistors you have in your bed and hot ends, and set them correctly, then you have a chance of accurately setting extrusion temperature.
Then, your heater settings. For full details see: https://duet3d.dozuki.com/Wiki/Tuning_the_heater_temperature_control
Your heater settings are at the default. It looks like you haven't tuned your heaters THEN sent M500 (to store them to config-override.g). Alternatively you can copy the heater tuning to config.g. This hasn't been done, as the heater profiles in your config.g are still:
M307 H0 B0 S1.00 M307 H1 B0 S1.00 M307 H2 B0 S1.00While the hot ends will probably heat up, the temperature control won't be smooth. So, tune heaters with something like:
M303 H0 S60 M303 H1 S200 M303 H2 S200Run them each a number of times, but wait for the heater to be at room temperature before doing it again. Once the results converge, send M500 to save them to config-override.g
Then either add M501 to the end of config.g so they load from config-override.g, or copy the heater settings to config.g
You can check the current heater settings by sending
M307 H0,M307 H1orM307 H2from the console.Ian

@droftarts Thanks. I thought they were correct when I see them at 18C degree. I'm using typical 100K Ohm NTC3950.

M308 S1 P"e0temp" Y"thermistor" T100000 B3950
I have added this into my config file the readings getting worst. Infrared thermometer shows 110 deg while the heater set at 200C. It is interesting not find a calibration easily for that thermistor.
-
@secure If it can melt filament, I'd trust the thermistor, not the IR probe, which measures the surface temperature. If it can't melt filament, you may have a faulty thermistor.

I searched and come with a very little information about this "ebay" thermistors on Reprap firmware so I made a little guess with IR thermometer.
I configured settings like below.

M307 H2 A498.2 C140.7 D2.9 S1.00 V25.2 B0I went from bang bang to pid for heated bed. It is a 220v silicone heater. In bang bang mode I can see the SSR lights blinks. Now in pid mode it is dimming the ssr light. I will further investigate this as I dont know which is safe.
Thanks

@secure said in Firmware 3.0 update. Heaters problem:
Now in pid mode it is dimming the ssr light. I will further investigate this as I dont know which is safe.
This will depend on the rating of your SSR. You can change the PWM frequency by using the Q parameter in the M950 command that creates the heater, eg .
M950 H0 C"bedheat" T0 Q100
See https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD#Section_M950_Create_heater_fan_or_GPIO_servo_pinEither that, or set it back to bang-bang mode, but keep the rest of the PWM settings, so it knows how long it's going to take to heat up, and doesn't fault, eg
M307 H0 A81.1 C180.3 D3.1 S1.00 V25.3 B1Ian
-
For AC bed heaters controlled by SSRs, I recommend you use PID with the PWM frequency set to 10Hz (Q10 in the M950 H0 command).

@dc42 Thanks captain that seems better now!
I'm using 100K NTC3950 sensor but I was thinking I'm on the the colder side. I've checked/ recalibrated sensor settings with my PID controller. When DUET shows 200C degree I was measuring 165C so I come up with settings

The thing very interesting is the extruder steps.
I had to change that lot. How could this be?2019 backup config.g file 2.04

What type of extruder are you using, and what microstepping in your M350 command?
-
Sorry this was my fault. My config.json file has 250mm steps so i edited via config tool(I like this) and missed that steps are wrong.
I need to figure out how to update config.json file.
-
@secure To edit config.json you'd have to load it up in the configurator, make changes, and save it out again.
Or just stick to editing config.g since it's human readable.
