Heat time doesn't works

[mungle]

I have an issue with the heat time... if i set it to 10 it doesn't print almost anything, if I set to 240 I'm getting the same results like I set 100...

I'm using this tiny printer from adafruit (https://www.adafruit.com/products/2751) so I don't know if I need to set different parameters...the model used for other raspberryPi project is Zijiang ZJ-58...hope you can help me solving this!
Thank you

Since that's a different model, it's quite possible that the initialisation codes required to set up heat time are different. It would be worth checking that, by comparing the code tables, but I can't tell from the Adafruit site what the actual make & model is...
