Basically, I want to set you and everyone else up for success.
#1 The most important rule in 3D printing is not unlike good housekeeping rules. You put away and reset back where it was anything you changed during the starting gcode by resetting it to an expected default in the ending gcode.
What is happening here, is that Ideamaker produced gcode and standard default profiles in it, will produce a gcode with potentially an M221 command at the start of a print that is NOT 100% flow rate. We also kind of now have the same problem with the fans as another topic, so I'm covering both for you since you may not have read that.
Why is this bad?
Well, the end of the print, the standard ending gcode is NOT returning these values to a known default.
Most other slicers- generally do not add and is not standard in most simplified starting gcode and assumes the printer defaults to 100% flow rate. So where you the user get screwed over here, is if you use both Ideamker and say another more normal slicing software and switch back and forth.
Again. the scenario is, you print a file with ideamaker and it sets the firmware active flow rate to say 90%. Then you print a Cura produced gcode file for your printer and it's now under extruded by 10% because the firmware was set by the previous ideamaker print job and then left at a less than 100% flow rate.
So what this means is, you have to develop a better system until they get this sorted out.
You need to add M221 S100 to the starting gcode of your other slicing software profiles so that they are reseting and ensuring rather than the common assumption that flow rate defaults to 100% in firmware.
You need to edit your ideamaker end gcode profile so that it properly resets the printer to 100% flow rate in case a lower flow rate is either commanded or inlcuded in the starting gcode.
The whole idea is that the firmware flow rate is meant to be a live while printing- oh crap, I'm under extruding because my filament doesn't match the setting used in the print file so I can live tune the flow rate. The assumption is 100% and lesser percentage reduces the flow rate in cases of over extrusion and over 100% extrudes more plastic to compensate for under extrusion.
Again, what you get here is ideamaker has bad habits, and in a mixed software and workflow environment, really wreaks havoc. Every other slicer just modifies the individual lines of gcode E lengths. Ideamaker both adds an M221 and edits lines of gcode for certain things. Worse, it can leave that altered M221 flow rate in active firmware memory and interfere with another slicers produced gcode because of bad housekeeping habits (not defaulting back o 100% flow rate at the end of the ideamaker produced print). So if you print say a Cura file first after booting your printer- you get the default 100% flow rate in firmware and the printer follows the gcode 1:1. If you first print an ideamaker file and don't add this ending M221 S100 and then also ensure you add it in your other 3rd party slicers, you can get where ideamaker set and left an altered flow rate, and then your perfectly fine print file suddenly over or under extrudes because of the previous print jobs flow rate left in active memory.
The fan thing is kind of the same problem for the gcode controlled print fan. Now, they also appeared to add some smart fan control that may alter fan speed mid print based on feed rate in a given layer. Kind of discussed here an unannounced feature that crept in. viewtopic.php?f=3&t=6299&start=60
Just saying, both of these (flow rate and fan settings) they affect user even not with Raise 3D printers.
