uncomment section below to use idle temperatures

[Rebekah_harper]

Hiya,

I have noticed the following and was wondering what it meant:

M218 T1 X0.0 Y0.0 ; reset extruder offset
T[new_tool]
M218 T1 X-18.0 Y0.0 ; set extruder offset
; uncomment section below to use idle temperatures
{IF NEWTOOL=0};M104 S100 T1 ; idle right extruder
{IF NEWTOOL=0};M104 S[extruder0_temperature] T0 ; heat left extruder
{IF NEWTOOL=1};M104 S100 T0 ; idle left extruder
{IF NEWTOOL=1};M104 S[extruder1_temperature] T1 ; heat right extruder

there is a line : ; uncomment section below to use idle temperatures

I am not sure what it means and what it does if I do what it says.

In my understanding that if I delete the section below it will use the idle temperatures during a dual extrusion print. But i've read a few post by experts that Idle isn't used on the UM3, which I know is the case currently.

reason I ask is that when using Cura 2.7, the PVA doesn't work well. it seems to have an extrusion issue and the frame work of the support fails. I have cleared a blockage from the nozzle and it still occurs. but with S3D it's fine. My concern is the issue raised in the post regarding S3D and not idling temperatures.

any advice is appreciated

{IF NEWTOOL=0};M104 S100 T1 ; idle right extruder
If the Tool is set to 0 the other head T1 is set to lower temp of 100. To reduce warmup time.

{IF NEWTOOL=0};M104 S[extruder0_temperature] T0 ; heat left extruder
Now that Tool is 0 we want to set the temp to tool 0 to the working temp

{IF NEWTOOL=1};M104 S100 T0 ; idle left extruder
If the Tool is set to 1 the other head T0 is set to lower temp of 100. To reduce warmup time.

{IF NEWTOOL=1};M104 S[extruder1_temperature] T1 ; heat right extruder
Now that Tool is 0 we want to set the temp to tool 0 to the working temp

hiya.

thank you, I appologise but I think I didn't express my self correctly.

it's more to do with the statement about uncomment below to use idle temperatures.

what do you have to do to "uncomment"

many thanks

Might want to give this a read:

It explains what all those commands do and what is used for comments

remove the ;
commented line
{IF NEWTOOL=0};M104 S100 T1 ; idle right extruder

uncommitted line
{IF NEWTOOL=0}M104 S100 T1 ; idle right extruder

Many thanks for that.

I have progressed now and have added additional commands as the 'wait for temp to stabilize' in the temperature tab doesn't work.

it continues to print before it's reached the temperature. I added a {IF New Tool} command relating to temperature stabilisation. it's not as good as Cura's intelligent way as it heats the nozzle before the nozzle switch but at least I can use S3D with the UM3.
