Hi,
With some try and also some error I managed to print spiral springs now, but just barely.
I’m printing the springs laying a their side.
So halfway the print you have a lot of small ‘islands’ which will become the spring coils:
o o o o o o
o o o o o o
This is where the problem starts, suppose I number the islands like this:
6 5 4 3 2 1
7 8 9 10 11 12
problem is that on islands 1 and 12 the printer always prints two layers two layers at the same island, before the first layer has the chance to cool down.
so printing sequence is: 1_2_3_4_5_6_7_8_9_10_11_12_12_11_10_9_8_7_6_5_4_3_2_1_1_2_3_4_5… (notice layers 1 and 12)
ideally it should be: 1_2_3_4_5_6_7_8_9_10_11_12_1_2_3_4_5_6_7_8_9_10_11_12_1_2_3_4_5…
Increasing layer time doesn’t help because the printer only prints more slowly (eg if you set min layer time at 35s, the printer calculates his print speed so one layer takes 35s, without having to stop printing. So islands 1 and 12 keep having two successive layers…
