Is Maslow GRBL?

Are we using a version of GRBL?

Thank you

No, we are trying to be grbl compatible, but grbl currently cannot support the
motor/encoder drives we are using, or the machine kinematics.

“we are trying to be grbl compatible”

Hi David,

any hope in the future ? how big this task could be ? any job taker ?

pure speculation based on Smoothieboard V2 with Arduino adapter module, would it be a GRBL version (like https://github.com/gnea/grbl-LPC)? or is it a step too far …



I ask because it could be nice to have some compatibilies, that open doors to some softwares like
laserweb
https://cam.openbuilds.com/?#

If it doesn’t already, Wiki/Github should have a document that maintains a Version Comparison/Compatibility List.

We should be noting intentional divergences, known issues, milestones, version parity, with GRBL and G-Code in general.

cheers,

any hope of switching to grbl? I have that hope :slight_smile:

there are two big things that need to be done to grbl

  1. create a motor driver that can be used instead of the stepper driver in grbl

This is good sized, but not huge. It’s something that will benefit grbl for many
other projects as well.

  1. introduce a new kinematics type

this is more complicated as the existing grbl infrastructure assumes that
movement is linear (either with traditional cartesian or coreXY) and our
triangular kinematics aren’t.

And then there is the issue of how to do calibration so that you don’t need one
firmware to calibrate and another to run.

smoothieboard is not grbl, it’s far more powerful.

Once the machine is calibrated, you can generally drive a maslow with anything
that can drive a grbl board. If you run into any problems, report them as bugs
and we will try to get them fixed ASAP

To be clear here I was pointing to the 2 firmware options (Smoothieware OR GRBL are the 2 firmware running on Smoothieboard).

Smoothieware:
You will find in the original Maslow funding campain a post From Arthur Wolf offering a Smoothie board to Any taker’s job to port kinematic / servo on Smoothieware. (it was too early, I think the servo have been done since, …)

GRBL: the 1.1 version have been compiled for LPC 1769 by Claudio Prezzi and run on Smothieboard (link provided). (the history is that one , I start the K40 community, modify a K40 on Arthur’s advice, then Peter Van der Walt join and develop LaserWeb, then Claudio (& others) take over, to improve it. Laserweb is now working with both firmware. fast rastering work best with GBRL.

The Smoothie Board V2 is an other matter it run on a faster ARM LPC 4330 so new Firmware (compilation). but the advantage of that one is within Arduino module support, you will not need much to host the actual Maslow shield (& library). But it’s still early stage …
