Issue #206 | 状态: 已关闭 | 作者: Y-uXiN | 创建时间: 2019-09-04

标签: help wanted

Please answer the following questions:

Have you read the wiki regarding how to compile?
Yes.
What version of the Arduino IDE are you using?
1.8.9
What version (commit date) of the Arduino core for the ESP32 are you using?
v1.0.2
Are you using the master branch of Grbl_ESP32?
Yes
Have you made any edits or configuration changes (list them) to the firmware?
Yes
Please paste the compiler error text here:
[MSG:Servo cal ($132) Error: 300.0000 s/b between 20.00 and 180.00]
[MSG:Servo cal ($102) Error: 800.0000 s/b between 20.00 and 180.00]
[MSG:Servo cal ($132) Error: 300.0000 s/b between 20.00 and 180.00]
[MSG:Servo cal ($102) Error: 800.0000 s/b between 20.00 and 180.00]
[MSG:Servo cal ($132) Error: 300.0000 s/b between 20.00 and 180.00]
[MSG:Servo cal ($102) Error: 800.0000 s/b between 20.00 and 180.00]

I have followed the step 1&2 on https://github.com/bdring/Grbl_Esp32/wiki/Servo-Axis-Feature
and made some modifications in the config.h and cpu_map.h
config.txt

That is not a compiler error. You are getting warnings because the servo calibration values for $102 and $132 are out of range. Please send $102=100 and $132=100 via serial console to put those values into the proper range.

Servos use those values to calibrate the end points of travel. The numbers are like a percentage. $102=100 would set the low end of the travel of the Z axis to 100%. 100% is essentially no calibration applied. If you set it $102=110. It would multiply the the pulse length of the lower end of travel by 1.10.

To make sure the calibration is not excessive, the range is limited to 20% to 180%.

Note: I added some additional notes to the Wiki.
