Model G0911–G0914 (Mfd. Since 05/21)
Symptom
Possible Cause
Possible Solution
Axis will not
move after
control panel
receives
commands.
1. One axis not moving.
2. All axes not moving.
3. Incorrect value(s) in RDWorks Vendor Settings.
1. Check connection to stepper motor. Check control
panel connection to controller. Adjust stepper
driver DIP switch configuration (
Page 82).
2. Check control panel connection to controller.
Adjust stepper driver DIP switch configuration
(
Page 82). Inspect/replace power supply to
stepper motors or faulty gantry components.
3. Contact Grizzly Tech Support.
Axis movement
and location
not repeatable.
1. Origin incorrectly set in artwork file.
2. One or more stepper driver(s) have incorrect DIP
switch configuration.
3. Guideway(s) contaminated or damaged.
4. One or more synchronous belt(s) are damaged or
binding.
1. Review RDWorks settings and verify that origin is
set correctly.
2. Adjust stepper driver DIP switch configuration
(
Page 82).
3. Clean and lubricate guideways (
Page 48). Inspect
guideway(s) for damage, replace if at fault.
4. Inspect/replace synchronous belt(s) (
Page 61).
Realign pulleys if necessary.
One or more
axes only
move in one
direction.
1. Controller/stepper motor connection loose.
2. Incorrect value(s) in RDWorks Vendor Settings.
3. Control panel/controller at fault.
4. Stepper motor(s) at fault.
5. Stepper driver(s) at fault.
1. Inspect connections and ensure all are secure.
2. Contact Grizzly Tech Support.
3. Inspect/replace control panel/controller.
4. Inspect/replace stepper motor(s).
5. Adjust stepper driver DIP switch configuration
(
Page 82). Replace if at fault.
One or more
axes will not
move.
1. Direction wire and pulse wire switched on
controller connector.
2. Stepper motor(s) disconnected.
3. Stepper motor(s) at fault.
4. No pulse signal from controller.
1. Rewire direction/pulse wire on controller
connector.
2. Reconnect stepper motor(s).
3. Inspect/replace stepper motor(s).
4. Inspect/replace controller.
Machine fails
to home, or
moves beyond
soft limits when
homing.
1. Incorrect value(s) in RDWorks Vendor Settings.
2. Faulty connection.
3. Proximity/limit switch not aligned.
4. Loose proximity/limit switch wire.
5. Proximity/limit switch at fault.
6. Controller at fault.
1. Contact Grizzly Tech Support.
2. Find/secure connection.
3. Inspect/adjust proximity/limit switch.
4. Secure connection.
5. Test proximity/limit switch (
Page 28). Repair/
replace proximity/limit switch.
6. Inspect/replace if at fault.

Auxiliary Systems Operations
Symptom
Possible Cause
Possible Solution
Auxiliary
system does
not start,
or machine
circuit breaker
immediately
trips after
startup.
1. Machine circuit breaker tripped or at fault.
2. Blown receptacle fuse.
3. Incorrect power supply voltage or circuit size.
4. Power supply circuit breaker tripped or fuse
blown.
5. Control/ground wiring broken, disconnected, or
corroded.
6. Power supply at fault.
1. Reset machine circuit breaker; connect auxiliary
systems to power supply separate from machine
(
Page 16).
2. Replace receptacle fuse/ensure no shorts.
3. Ensure correct power supply voltage and circuit
size; connect auxiliary systems to power supply
separate from machine (
Page 16).
4. Ensure circuit is sized correctly and free of shorts.
Reset circuit breaker or replace fuse.
5. Fix broken control/ground wires or disconnected/
corroded connections.
6. Inspect/test/replace if at fault.
