Thermocoupler reading odd - CTC sailfish
Posted: Mon Jan 13, 2020 8:25 pm
I got a CTC standard replicator clone with Sailfish installed. a while back the thermocouple broke which happens every so often when the wire gets a bit too close to the hot end and kinda burns through.. anyway.. nothing odd there..
But when I connected up a new coupler, it was erratic with it's readings, then, when I was told to look at adjusting the PID settings, it fixed itself in away.. settings were now stable.. but aren't right.. When printing at 190 (which I normally do), there were ALOT of strings and some spikes.. so I tried lowering the temp.. and I've got it to 160, and its still doing the same thing, though much lesser (though it's a bit colder right now and it's being a bit worse again).. I also had tried going higher, but to no real effect. I have replaced the coupler, trying a few ones, and no difference was noted.
While these are couplers I normally use and don't often have a problem, stock ones had different metals.. one was a silvery metal and one more copper, but the only ones I can find (and what I normally end up using) are both different silver coloured metal mixes..
anyone have any ideas? I don't think the sensor chip on the board has gone bad.. and it would be really annoying as it's a fairly new board, but.. I'm not sure what's up if I can't seam to make a difference
