[Grbl_Esp32 Issue#728] Limit Invert Mask About GRBL HAL

Issue #728 | 状态: 已关闭 | 作者: reynolds087 | 创建时间: 2021-01-03

Hi, I see this line in the roadmap under recently completed:

Automatically generate #define LIMIT_MASK from defined pins.

Does that mean that the feature is available, or is it still in progress? I have a mixture of normally open and normally closed limit switches. It would be difficult to change that. If not, is there another work around for my situation?

See this wiki page on how to do that.

Stay tuned: This is about to get way better in the next major update.

Thanks, is the example on that page meant to be literal? for instance if I want to only invert the x and z limit switches, would I use this line?

#define INVERTLIMITPINMASK ((1<LIMITBIT)|(1<LIMIT_BIT))

It won’t compile the way it’s shown on that page. I’m sure I’m doing something wrong, just can’t figure out what. I copy pasted the example line from the wiki and get this message:

sketch\src\Limits.cpp: In function ‘AxisMask limitsgetstate()’:

sketch\src\Machines/josh.h:108:36: error: ‘XLIMITBIT’ was not declared in this scope

#define INVERTLIMITPINMASK ((1<LIMITBIT)|(1<LIMIT_BIT))

^

sketch\src\Limits.cpp:331:16: note: in expansion of macro ‘INVERTLIMITPIN_MASK’

pinMask ^= INVERTLIMITPIN_MASK;

pinMask ^= INVERTLIMITPIN_MASK;

I guess I was overthinking it. Set it like other axis masks, and it worked. I put 2, because I actually only needed to invert my Y axis.
