In our setup, Mach3 sends pulses to the a servo driver which moves each servo while monitoring the axis' reported movement via direct feedback from the rotary encoder, at a resolution of 128ppr (x4 = 512). <ref>https://forum.protospace.ca/t/cnc-router-acting-funny/243/29</ref> That part of the system is “closed loop”. | In our setup, Mach3 sends pulses to the a servo driver which moves each servo while monitoring the axis' reported movement via direct feedback from the rotary encoder, at a resolution of 128ppr (x4 = 512). <ref>https://forum.protospace.ca/t/cnc-router-acting-funny/243/29</ref> That part of the system is “closed loop”. | ||
However, Mach3 doesn’t know if the servo kept up or not and if the machine is in the expected position.

The servo driver knows if it went as far as it was commanded, but if the discrepancy gets too large, all it can do is raise an error signal or shut down the driver. When this happens, the "machine" no longer knows where it is and must be rehomed (Ref All) to the limit switches. | ||

===== "ESS did not respond to wakeup message" Dialog box appears when starting Mach3. ===== | |||
This usually means the large black controller box for the machine is turned off, or did not have enough time to start before starting Mach3. | This usually means the large black controller box for the machine is turned off, or did not have enough time to start before starting Mach3. | ||
===== | ===== "The ESS has an invalid bootloader signature" Dialog box appears when starting Mach3. ===== | ||
This happens when Mach3 didn't shut down the controller correctly. Power off the controller, wait some time, power on, launch mach3 again. This can happen if someone is logged in with mach3 running in the background, comms are impossible, and a reboot has to be used. | |||

Green light -> Power. Switch is on small box beside the controller box. Circuit breaker is on the East wall labelled Precix. | |||
Red light -> Drive fault. Press the light/button to reset. | |||
Sometimes the serial port on the PC gets into a weird state and comms are lost to the drive. A full power off, power on reset of the PC is needed to clear this problem. | |||

===== Ethernet SmoothStepper ran out of data in the middle of a move ===== | |||
Briefly, run your file from the hard drive, and when your job is running don't mess with the computer. | |||
* '''Best Practices''' | |||
** Make sure your GCode is running from the hard drive. Never run GCode from a network drive or a USB stick, at some point, there will be a pause while trying to access the data and the ESS will run out of data! | |||
** Don't switch screens or applications while running GCode | |||
** Try not to zoom, pan / orbit the view port (3D preview) while code is running | |||
** Don't refresh your tool path while running GCode | |||
** Close all other software when running Mach3 (so they won't consume RAM or CPU time) | |||
* '''Advanced Options''' (consult with the Protospace local Precix experts before changing hardware/firmware settings) | |||
** Replace platter HDDs with SSDs | |||
** Run [https://warp9td.com/index.php/faq/faq-windows#HigherPriorityLevel Mach3 at a higher priority level]. This is done in the SCU's Windows Performance Tuning | |||
** Make sure that the [https://warp9td.com/index.php/faq/faq-mach3#MachThreeControllerFreq Controller Frequency] is set to a reasonable value. | |||
** Warp9 reports that electronic noise or ground loops from the dust collection or VFD may cause issues | |||
** Do an air cut and check how hard the CPU and RAM are working. If the computer is struggling, pitch an upgrade on the forum! | |||

===== The machine has lost its way ===== | |||
The driver/encoders can lose sync with Mach3 under the following conditions:<ref>https://warp9td.com/index.php/faq/faq-mach3#DROs</ref> | |||
* Mechanical Backlash (root cause is hardware) | |||
* Incorrectly configured Software Backlash Compensation settings | |||
* Pressing the physical E-Stop button while motion is in progress | |||
* Pressing the Mach software <code>Stop</code> button while motion is in progress | |||
* Improperly tuned acceleration or velocity settings that cause slippage on an axis | |||
* Power was removed from the motor drivers, and the axes drifted or moved from their set position | |||
===== | ===== Spindle won't reach all the way down to the table ===== | ||
Someone removed the 6 screws that hold the spindle motor plate to the Z axis and raised it 2 inches. Move it back down. | |||
===== You can help expand this list by hopefully not breaking the Precix too badly! ===== | |||
