IP stands for Ingress Protection and it is a system of rating to show the levels of sealing against foreign bodies. This standard of rating is used for electrical enclosures to tell us how safe that enclosure is from external elements like moisture, dust, etc.
The spindle runs at full speed regardless of the speed control potentiometer or even the Spindle on/off switch. The board or the components don't have any obvious burn marks and the fuses are intact. I have disconnected both the on/off and the speed control and it still runs.
If you put the switch in the off position, this puts a logic low on the gate of the FET turning off the motor. If you put the switch in the off position and the motor still is running, you have 1 of 2 problems.My Genmitsu/Sainsmart 3018 Pro has gotten in a state where as soon as I connect 24v power, the spindle (a Genmitsu brand 20,000 RPM spindle motor) immediately spins at full speed. .My Genmitsu/Sainsmart 3018 Pro has gotten in a state where as soon as I connect 24v power, the spindle (a Genmitsu brand 20,000 RPM spindle motor) immediately spins at full speed. There is a keypad button that should turn the spindle on/off in manual, but I don't see any RPMs shown anywhere and nothing happens at the spindle, though S-ON/SOFF .

Make sure you have the correct correct information in Config - Ports N Pins - Motor Output - Spindle. The light on the diagnostics screen will light up, but if you do not tell it where . Can you control the spindle independently of the CNC controller? Check the wiring for errors/loose connections/etc. Is everything getting power? Check twice. Then tell us what .
Sometimes the spindle or turret will "sag" after a machine is shut down, if oil or air is able to bleed from the system once power is cut. That's why you hit the E-stop.it locks the machine axes .

Neither my offline controller nor a M05 gcode command will turn it off, although toggling the spindle on the offline controller causes the "spindle" LED to turn on .
I've had my machine for over a year and half now with little to no problems. Just the other day i was running a job - and accidentally set my z level too low and in the middle of the job, the bit hit the bed and snapped. My Genmitsu/Sainsmart 3018 Pro has gotten in a state where as soon as I connect 24v power, the spindle (a Genmitsu brand 20,000 RPM spindle motor) immediately spins at full speed. There is a keypad button that should turn the spindle on/off in manual, but I don't see any RPMs shown anywhere and nothing happens at the spindle, though S-ON/SOFF display changes. As I've been able to parse the manual, one should be . I just now tried setting the spindle at 200rpm and turning it on/off and forward/reverse directions. I noticed if the spindle stops in a certain orientation it won't start but it will beep the high frequency sound while pegging the load meter until the relay or contact pops, requiring a reboot.
Not turning off is probably due to the burnt PCB. You probably cooked a power control chip and now instead of switching it now is stuck in an open state. You may have cooked it because you made a short circuit or intermittent short inside your spindle. I have a 3018 pro cnc machine. on attempting to router engrave a nameplate today with the easel program, the spindle failed to turn. I have successfully tested the motor with a 9 volt battery and also checked the conductivity of the cable from the motor back to the control panel with no problems.
