Title: first BCL-run with LaserBot gives no movement/laser (RESOLVED)
Post by: ivo on August 08, 2018, 11:38:43 AM: Hello,
I have a Makeblock LaserBot.
My LaserBot works with mlaser. But I am searching better SW due to the many bugs/limitations.
I want to make a test if laserbot works with BCL before buying the license, is this possible ?

I have installed BCL but can not have any movement in my laserbot using BCL.
I installed BenCutLaser Version 3.2, and flashed the Marlin_110_RC8_FA_BL.hex firmware into Laserbot. (OK, no errors)
I have set next parameters:
COM Port - set COM5 - set MinMega2560
COM Port - 11520, no parity,, 1 stopbit, 8 databits, no handshake
Setup - Controller boards - set "MegaPi/LaserBot"
G-code Generation - settings - GCode parser: BCLVLM_Marlin
Laser Tool parameters - set "Normal laser operation"

I get no movement with next commands:
Laser Tool Parameters - click "Left/right test" -> no movement
click circle test -> no movement.

I get below startup messages when I connect, so connection is OK I think:

For instance:

"$$"
should list the current operational parameters while

"G00 X10 Y20 F600"

should move the laser head to position (10,20) at speed 600mm/min.

BTW - you might want to manually position the head in the center of the fixture prior to playing.

Another option is the universal gcode utility.

Post by: ivo on August 09, 2018, 11:33:29 AM: Thank you for al your feedback!

All parameters are like on the images.

Terminal mode was a good idea. Here I get action !
I get next response in terminal-mode:
"G00 X10 Y20 F600" returns "ok" and moves the laser head (greath ! it is still alive !)
"$$" returns "echo:Unknown command: "$$" " [LF] "ok" (maybe not supported by Marlin)
"M115" returns:
      FIRMWARE_NAME:Marlin 1.1.0-RC8 FA BL (Github) SOURCE_CODE_URL:https://github.com

"M114" returns:

"M503" returns:

      echo:Filament settings: Disabled
      echo: M200 D3.00
      echo: M200 D0

So:
- HW & communication is working
- but commands from insde BCL are not done, except at connection time !?

The communication speed in BCL and terminal mode is 115200. is this maybe too high for BCL ?

I get now always the "Microsoft.NET framework" Unhandled exception error when
- starting BCL
- clicking the Toolpaths-tab

I have re-installed BCL and reflashed the firmware -> no better results; Unhandled exception error and no movement of the laser.
Do you have any other sugestions to do/test ?
Best Regards,
Ivo

Here are some screenshots:

Post by: ggallant571 on August 09, 2018, 12:09:39 PM: It appears your units are mm/sec. Not a problem but the typical is mm/min. BTW - mm/sec seems a better term!!!

Post by: ivo on August 09, 2018, 10:28:19 PM: Hello Ralph,
I am in Brussels/Belgium/Middle-Europe: GMT+2, 9 hours ahead of you.
OK for a screen-share. I am not home until late this evening. I let you know when available.
Thanks for your time & support !

I check the mm/sec mm/min when I am back home.

Post by: ivo on August 15, 2018, 02:28:32 AM: Hello Ralph,

I finally succeeded in getting BCL operational (head moves and laser on/off) with Laserbot.

I did a new download and installation on a second PC without any BCL run-time problems.
I un-installed BCL, rebooted, and installed again with the new download on the problem PC. This time all worked OK.

The only difference I see is that BCL on the working installations shows default communication parameters (115200 baud PARITY=N DATA=8 STOP=1)
while the problem installation showed at startup zero-communication parameters which I corrected after each startup.
Is it a bad download or an installation issue, I do not know, but I can continue with my first full test.

Thanks for your support !
Ivo

Problem: BCL does not send any command to the laser but receives the laser boot-messages, COM-port communication parameters are all 0 at startup of BCL
Configuration Makeblock LaserBot + BCL, Win10
Solution: new SW-download, BCL-uninstall, PC-reboot, BCL-install

Post by: Administrator on August 15, 2018, 08:16:32 AM: I'm glad you finally got it working. For those unaware, @Ivo and I had an extensive off-forum support exchange going for a couple of days.

Make sure you are installed into Bencutlaser folder. It sounds like BCL is not able to save your comm port parameters and that's the only reason I can think of for it not being able to do that. BCL must be installed into that folder.
