Setting Print and Bed temperatures in start code

@dc42 My Homedelta file looks like this:
; homedelta.g ; called to home all towers on a delta printer ; ; generated by RepRapFirmware Configuration Tool v2.1.8 on Fri Feb 21 2020 19:36:19 GMT+0000 (Greenwich Mean Time) G91 ; relative positioning ;*** Slow homing has been configured. Change F180 to F1800 below when your configuration is working G1 S1 X483 Y483 Z483 F1800 ; move all towers to the high end stopping at the endstops (first pass) G1 S2 X-5 Y-5 Z-5 F1800 ; go down a few mm ;*** Slow homing has been configured. Change F180 to F360 below when your configuration is working G1 S1 X10 Y10 Z10 F1800 ; move all towers up once more (second pass) G1 Z-5 F2400 ; move down a few mm so that the nozzle can be centred G90 ; absolute positioning G1 X0 Y0 F2400 ; move X+Y to the centre -
Add a T0 to the start of your startcode to ensure your first tool is selected. Your homedelta looks fine. How bout your bed.g that gets called by g32?

I'll add the tool at the start and see what happens on the next print. My bed file looks like this.; bed.g ; called to perform automatic delta calibration via G32 ; ; generated by RepRapFirmware Configuration Tool v2.1.8 on Fri Feb 21 2020 19:36:19 GMT+0000 (Greenwich Mean Time) M561 ; clear any bed transform G28 ; home all towers ; Probe the bed at 6 peripheral and 3 halfway points, and perform 6-factor auto compensation ; Before running this, you should have set up your Z-probe trigger height to suit your build, in the G31 command in config.g.

Use S4 for endstop heights and Z-height only. Use S6 for full 6 factors ; If your Z probe has significantly different trigger heights depending on XY position, adjust the H parameters in the G30 commands accordingly. The value of each H parameter should be (trigger height at that XY position) - (trigger height at centre of bed) -
bed.g looks ok as well.

I dont know, now no matter what I do the Hot end temperature is not set. I have tried
G10 P0 S{print_temperature} G10 P1 S{print_temperature}as I am not sure if Pnnn is refering to the heater number of the Tool number so I have tried both
Simplify3D also adds its own start code in the form of:
G90 M83 M106 S0 M140 S120 M190 S120 M104 S230 T1 M109 S230 T1The start code in the Model GCode file looks like this at the moment

Just the one.

So P0 is correct as I only have 1 tool?

No, I am sure of nothing but I think it used to work. I should RTM I guess.
@Phaedrux said in Setting Print and Bed temperatures in start code:

In Simplify3D in the Temperature Tab you can select the Temperature Identifier but the BED is T0 and the extruder is T1 I think but then you also select the Temperature Contoller Type of Extruder or Heated Bed so maybe that identifies it and it should be T0 for both. I really don't know, I was hoping someone else did.

Yes, this is my config.g

@KeithW This may or may not help you but I've kind of given up on using the slicer to do anything other than generate the gcode for the print. That is to say, I no longer use the slicer to set tool or bed temperatures but simply have one line in the "custom gcode section" which calls one "pre print" macro and one "post print macro". I have a number of these macros which only differ in the actual temperature values. The main reason for doing this is that it gives me much better control over what happens and when. For example, the first thing the macro does is set the bed temperature to 40 deg C and wait (M190 S40). Once the bed reaches 40 deg C, it then sets the bed temperature to the required print temperature (usually either 50 or 60 deg C) but does not wait (M140 Snn). While this is happening , it runs my home all macro (G28) then heats the nozzle by using G10 S and R and selecting a tool. Finally it waits for all temperatures to reach their set values (M116). The net result is that the homing, hot end heating and everything else gets done in the time it takes to heat the bed. There is no extra wait for one thing to reach temperature which another is heating but at the same time, the hot end does not sit there at print temperature any longer than is necessary.
The other thing about using macros in this way is that they are "slicer agnostic". That is to say, all you have to do is call the macro from whatever slicer you happen to choose. So you can swap between slicers without having to delve into their own methods of setting temperatures (other than disabling them - setting them to 0 works in Slic3R and it's variants). It also allows hot end active and standby temperatures to be set "correctly" using G10 S and R.
I don't know if that helps, but if it does, I'd be happy to share my pre and post print macros.
-
So how do you deal with all the differing Print and bad temperatures? Do you specifically call the macro in the Slicer profile and have a different on in config.g for each scenario? I only ever use Simplify3D so I am not specifically bothered about it being slicer agnostic but if it is easier then I am all for it.
I would like to at least try your solutions so if you would share the macros that would be good.

Yes, I have different macros for different bed and hot end temperatures. There aren't all that many combinations. Now that we have conditional gcode, I could probably simplify that but I haven't had time to look at that yet. Something along the lines of "If filament type is AAA then set be temp to XX and hot end to YY, else if" ....etc
For now, I just need to remember to call the correct macro from the slicer start gcode. But another advantage is that if I sliced an object and printed it with PLA, if I wanted to print it using say PET-G and the only differences are the hot end a bed temperature, then all I have to do is edit the line at the start of the gcode to call a different macro.
Things are little more complicated for me because I use multiple tools and a mixing hot end but here is an example of a macro which sets the bed to 40 and waits, then sets it to 50 and runs home all and sets the hot end to 185 .
M291 P"Heating bed" R"Pre-Print Macro" S1 T10
M190 S40; start heating bed and wait for it to get to 40
M291 P"Homing all axes" R"Pre-Print Macro" S1 T10
M140 S50; Now start to heat bed to 50 but don't wait
G28 ; home all axes while completing bed heatT0 ; select a tool
; Set operating and standby temps
G10 P0 S185 R185
G10 P1 S185 R185
G10 P2 S185 R185
G10 P3 S185 R185
G10 P4 S185 R185
G10 P5 S185 R185G1 X80 Y363 F9000 ; move to rear
M83;M291 P"Waiting for heaters to reach active temperatures" R"Pre-Print Macro" S1 T10
M116 ; wait for all temps including hot end
The M291 commands are just messages which are optional. The 28 runs the home all macro so you can call other macros from within a macro. Actually, I also call another macro to wipe the nozzle once the temperatures are up to their set point but I omitted that from the above example.
In slic3R I set all the temperatures to zero which suppresses any M104, M09 , M140, M190 commands. Then I just have this in the custom start gcode.
M98 P"0:/macros/PrePostPrintMacros/PrePrint9ToolBed50T185"
The end gcode links to a separate macro which basically just turns off all the heaters (M140 S0, G10 S0 R0).

So does it matter what the file extension of the macro is? Do you upload the macros to the printer?
-
@KeithW Macro files can be ".g" or you can leave them blank with no extension. I like to upload macros to a "macros" folder on the SD card. When you call a macro, just put the full path in - like the M98 example above. In my case I have a "macros" folder and within that I have a folder called "PrePostPrintMacros".

@KeithW I think this is the S3D format.
M104 S[extruder0_temperature]
M140 S[bed_temperature]
Hope this helpsI use macros in my start up as well as @deckingman

@deckingman @appjaws @dc42 Thanks all, I think between all this there is something I can use.
I will look at the macros tomorrow. In the mean time my PrintBite has a bubble under it now for some reason after 4 years of use so I have to take it off and reapply it so a night of removing adhesive is on the cards.

Ok so then I think part of the problem is the M104 T1 that you're getting out of S3D. I'm not a S3D user, but You'll have to change it so that it's only outputting T0 commands.
If you combine that with Appjaws variable formatting for S3D I think you'll be good to go without having to go the macro route.
