Extruder temperature problem (160 deg)

[modeljjy]

Hi, this is James. I have a question about the extruder temp. I have a Lulzbot TAZ 4 model with one extruder.
The temperature of extruder is not risen up to the desired temperature (220 deg) for ABS, just remaining within 160 deg. I already changed the extruder, heat resistor, and firmware. But same results. I do not think the mainboard (RAMBO v.1.3.) have the problem.
Today, I found some messages in Cura.

Here are the message:

Somebody help me! I really want to fix it. If you have a solution, I will give a reward for any way.

Can you post your configuration.h etc for people to look at please? Also what temp does it show when at room temperature?

Ether its extremely cold,
or your thermistor is unconnected now.

Im having a similar problem. Everything looks good, bed heats but extruder never quite makes it, gets to within 10 of set temp then goes down and up forever

[o3dodgesrt4]

similar issue here on my delta... target temp is 220... gets to 200-206C and then turns off and hard reboots... sometimes it just fluctuates and never stabilizes... even after a auto PID tune... iv replaced the hotend (E3dv5) with the complete E3Dv6 kit and still had the same issue..then i replaced the ramps 1.4 with a known working one from my mendel90, and same issue...iv been fighting it for weeks now trying to figure it out, but to no avail...

Do you see this problems with version 1.0.2 or just in the current RC? There have been some changes to the thermal-protection code. However, the heating itself should still be reliable.

[bobsalter]

1 and 1.0.2 run perfectly. Problem for me is only in current RC

current RC for me as well.. im using 1.0.2 right now and it works fine for my delta... whats weird is that the current RC seems to work just fine for my mendel90 but not my delta...both printers using the same equipment, RAMPS1.4, full graphics lcd, e3dv6 performance kit, mechanical endstops, heaters are identical brands and watts, Temp sensors are identical brands and resistances.

Y'all should try the RCBugFix branch just to confirm this hasn't already been fixed (either intentionally or as a side-effect).

I'll just post these links here for our convenience:

• Changes between 1.0.2-1 and RC2
• Changes between RC2 and RC3
• Changes between RC3 and RCBugFix

It also occurs to me that we can look at the History for an individual file. So we should especially review commits to temperature.cpp if it comes down to that.

Meanwhile try to isolate the issue by turning options on and off. Settings to play with include USE_WATCHDOG, THERMAL_PROTECTION_HOTENDS, THERMAL_PROTECTION_BED, PIDTEMP, BANG_MAX, PID_FUNCTIONAL_RANGE… probably some others. This will help narrow down the cause.

Thank you for your interest making Marlin better and reporting this issue but this topic has been open for a long period of time without any further development. Marlin has been under heavy development for the past couple of months and moving to it's last mile to finish the RC cycle and release Marlin v1.1.0. We suggest you to try out the latest RCBugfix branch and reopening this issue if required.

[o3dodgesrt4]

Yup no prob. Close it if it wasnt already..
