[Grbl_Esp32 Issue#416] Serial COMM only in Testdrive About GRBL HAL

Issue #416 | 状态: 已关闭 | 作者: wayneosdias | 创建时间: 2020-05-31

Im having issue w getting serial comm to work w the machine defined anything other than testdrive.h. When test driving tx rx work using the general GRBL commands. Using Machines/3axisv4.h or any other variant with in the machines folder and ESP32 only txs board properties on hard reset. The module doesnt seem to rx commands. Im not experienced w the Arduino IDE and dont care for it much.

Can someone help me get rolling. Im after a 4 axis setup with a pair of low freq gpio for controlling relays, switch frequency is not important. Can someone share a working machine file?

We have no information to help us debug this problem. Please paste your startup text in a reply.

What hardware have you connected the ESP32 to? The machine definition file you are using requires specific hardware attached or floating switch inputs could be locking up the ESP32.

Hi Bart,
Sorry, Im using a original Espressif board the “ESP32Coreboard_V2″ and have duplicated the issue on a ESP-WROVER-KIT V3 board. Startup text appended at bottom of reply

Ive made some progress and have full TX RX working on a modified 3axis_v4.h file. I started by commenting out everything, recompiling and sequentially uncommenting each line. Ive gotten all the step/dir gpio uncommented w full TX RX. Comms are working but I havnt checked gpio hardware just yet. The end application is a CNC router with Clearpath servos.

Ill push on to the uncommenting ifdef’s but first I want to try and figure out how use the Arduino IDE. Now Im using Visual Studio to modify Arduino file and unable to step thru, its taking too long and is clumsy to get thru…

You did not answer my question, but it does not appear that you do not have the ESP32 connected to a CNC controller board.

It appears you have shown my the startup text after you made changes that made it work better. That does not help me.

Do not use pins 34-39 for anything unless you have resistors attached. https://github.com/bdring/Grbl_Esp32/wiki/Setting-Up-the-I-O-Pins#input-only-no-pulluppulldown

Hey Bart, no hardware, cnc controller breakout or otherwise is connected to the ESP32, Its just a ESP32Coreboard_V2 connected to PC via a USB cable.

Heres boot text for RX not working (“#include “Machines/3axis_v4.h”, no response to $$):

Thanks…easy fix when we get the info.

you cannot use pins 34-39 without attached hardware with pullup resistors. A floating I/O pin has told Grbl that your door is open.

Comment out all these pins.

“#define CONTROLSAFETYDOORPIN GPIONUM_35 // labeled Door, needs external pullup #define CONTROLRESETPIN GPIONUM34 // labeled Reset, needs external pullup #define CONTROLFEEDHOLDPIN GPIONUM_36 // labeled Hold, needs external pullup #define CONTROLCYCLESTARTPIN GPIONUM_39 // labeled Start, needs external pullup“

Workin now Perfect, thanks. Thanks also for your work on the psoc grbl port too Do you want me to donate or would you prefer I buy your product on Tindie?
