I would not be able to give you an answer on the reason. One thing to keep in mind is that when changing temperature (some people need to print their first layer at a different temperature than the rest) it's not allowed to just "stop and wait" until the temp has been reached. It will leave a mark on the product and if the nozzle is removed to prevent that it will leak, result being less material when printing continues. So after the first layer, a new temp is set without stopping the movement. Is above possible (changing spindle speed without stopping the movement)? > > This is one of the things that has annoyed me about the RepRap folks, they > go inventing a bunch of M-codes to do what standard codes should already be > able to do in a proper controller. > > > On Fri, Apr 18, 2014 at 5:05 PM, Bas de Bruijn <[email protected]>wrote: > >> >>> On 18 Apr 2014, at 21:39, Bas de Bruijn <[email protected]> wrote: >>> >>> Hi, >>> I'm working on remapping M109/M106/M104 to something like M209 etcetera. >> I came across thishttp:// >> reprap.org/wiki/Talk:G-code#M104_.26_M109_Deprecation.2C_G10_Introductionand >> I'm wondering about the way to continue. >>> >>> The M104 used in reprap style devices is for setting the temperature of >> the hot end, and M109 will also wait for the temperature to be reached >> before continuing. >>> >>> I'm wondering what is the right way to go. >>> How do you normally use tools which are heated?
