4. ss = Switch Status
The ss diagnostic message reports system status. The controller outputs a
report on optical and mechanical switches to the terminal window.
Use this for checking:
• Printer Gender (sent either wrong system software or .CAL file to
printer).
• Motor gear ratio (if the system does not home correctly, the gear
ratio could be changed from cable table to belt table).
• Head temp set point (with MaracaEX you can change the temp to
not match system software specification, causing errors).
• System Software version check.
This is the Average distance in inches between the sub-
strate and the Z BOT sensor. The machine is looking
for the planarity of the substrate, if the substrate is not
flat, then the machine will not home.
This is the lowest distance in inches between the sub-
strate and the Z BOT sensor.
SR64K type Z-Stage detected means, that the Z-Stage
has a Gear Ratio of 64000 microsteps per inch. This
indicates either a three leadscrew Z-Stage or a single
leadscrew Z-Stage.
