nozzle osse wipe off in firmware November 04, 2015 04:27AM |

Hi all and mostly dc42
I have a four nozzle set up and I have minor ossing problem that appear 1 min after nozzle change and then stops.
Would it be possible to write custom g code xx time after nozzle change?
If possible I could move the head to a wipe of point and get rid of the osse
Slicer has an option for custom g code on layer change but layers can have a long duration.

Yes, you can add your own gcodes to the tool change files. What commands do you have in the tool change files at present, what filament are you using, and what standby nozzle temperature?

I am using a home made water cooled nozzel system and I am doing 5 mm retrac, so the ossing I have is only the filament left in the heater block.
I am only going to xy change tool wait for temp for the new tool and then starts printing again, I am using the same standby temp as printing temp.
What I want to do is 30 sec after toolchange and 60 sec after toolchange i want to ad custom gcode to wipe off the ossing. I the time between i want to print.

To prevent ooze you need to use a lower standby temperature than printing temperature. I use 150C standby temperature for PLA.

Yes but I only have ossing for 1 min so my idea is to wipe it of after that is cold enough 5 mm up so the ossing stops.
If I can maintain printing temp i can have faster printing.
Would it be possible to have that in the firmware so you can write custom code based on time after tool change.

Why not just put a delay in your tool change G-code?
[reprap.org]
I'm not sure what the max value it can take, you will need a parameter of 60000 (G4 P60000) for a 1 minute delay. If it won't take that large a value, stick a few shorter delays one after the other.
You can also move the head to a wipe point in your tool change code.

I want the printer to print during this time, maybe I should check more into slicer settings.Quote

I run with four nozzles so there can be up to four tool changes on each layer so quick tool change is important.

DC, when the tools change, is there a 'Wait till Temp xxx' put in by Slic3r? Or is it handled by the Firmware when it sees a new temp setting for it? I'm nearly at the stage of running the two nozzles now, but haven't solved my problem here yet. Hopefully over the weekend I might be able to solve it. But I haven't notice the printer waiting when it changes tools to heat up the new tool.

I haven't used slic3r for some time, but I don't think it puts a wait-for-temperature command in the gcode by default. You can put one in the tpost tool change files if you like. I use M116 P1 P0 in tpost0.g so that when changing to tool 0 it waits for the hot end to heat up but doesn't wait for the other one to cool down. Similarly I have M116 P2 P1 in tpost1.g.

AFAIK the P parameter of M116 specifies the tool number, so you'd in fact have to put M116 P0 in tpost0.g and M116 P1 in tpost1.g. At least this is what I've been using on my dual-nozzle Ormerod 2.
Quite right, I had forgotten that the P parameter is the tool number, not the heater number.

Many thanks DC / Zombie, I've added the tpost.g files to my sys folder now, didn't know about them before. Hoping to get some free time on Wednesday to get the printer going again so having the files in place is a bonus. Many thanks.
