Hi, I’m new here.
I’m relatively new to 3d printing, and have a ctc dual after previously using a geetech delta printer (which was too badly made to ever print accurately). I’ve been printing non stop with the ctc and I’m happy with my set-up but have only recently started looking at using the second extruder. I’m running Sailfish 7.7, and using the Makerware software as a slicer at the moment.
I have recently solved the problem with the left nozzle trying to print through a cold extruder on duplicated settings profiles.
However when ever I use the left extruder (for support material or as the sole extruder) the head and the bed crash into the side/bottom of the printer (the head goes to extreme right (against stop switch) during the initial “wipe” and if I cancel a print the bed crashes into the floor and the head crashes back left.
On exactly the same settings, same profile same 3d model (but without supports on the left extruder) prints fine on the right extruder with no crashing, and parks after printing (or cancelling) in the normal back right, z 10mm or so off the floor.
Any ideas? have I perhaps got something wrong in the firmware settings when I did the sailfish upgrade (I hadn’t worked out the cold nozzle probem before the upgrade to sailfish so don’t know if the problem existed before)? (I’m thinking the dual nozzle offsets? do the extruder have 2 separate print areas?)
Thanks in advance.
At least part of your problem sounds like a toolhead offset issue. They may be wrong or blank.
If your right extruder works fine, write down your home axes from the printer settings.
Measure the difference between the two extruder heads (or look it up for your model).
Then, check your toolhead offsets. Is it the home axes minus the difference between the left extruder and the right?
I had a similar issue in the x plane and found that the settings were off by a factor of ten. I’ve got a different printer than you, but I’m running sailfish and that fixed me.
Not sure about the z plane issue, sorry!
