I have been looking at how to create a machine where the medium is inserted in to one side, a type of encoder (actually a micro switch) counts the distance on the feed roller and once in position the G code for the X/Z is run. I set up exactly what I needed in Mach3 and seems to work a treat however its not exactly a portable option and with most laptops not having a parallel port this makes things a little awkward. In short i set up an M code that had a P var and this represented the switch triggers to wait for before executing the next line. in the test 1 click = 1mm. So G1 Z100 X0.1 M667 P30 G1 Z0 X0.1 the first line would run, then the M code would wait for 30 triggers on the switch then the next line would be run Initially I looked at GRBL however kind of got really lost in the code as my programming skills are not overly advanced, Now i am looking at teacup as there seems to be a lot more people using it and its a little more active. I would really appreciate some assistance with this one. https://reprap.org/forum/read.php?147,498595,498595#msg-498595 Thu, 16 Jul 2026 03:24:24 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?147,498595,498595#msg-498595 https://reprap.org/forum/read.php?147,498595,498595#msg-498595 In short i set up an M code that had a P var and this represented the switch triggers to wait for before executing the next line. in the test 1 click = 1mm.


So
G1 Z100 X0.1
M667 P30
G1 Z0 X0.1

the first line would run, then the M code would wait for 30 triggers on the switch then the next line would be run
