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.
Figure 441: Switch status
Average surface: 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.
Lowest surface: 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.
