Hi @Frank_Soloman, Webcontrol is not yet ready for the Arduino Due as far as I know.
If there was a roadmap, my guess would be that it will get GRBL ready for the Mega first as there are far more users already.
Ok thanks for the info.
If I was set on using Webcontrol as is, would it be as simple as buying new electronics?
Wouldnât the motors, etc all still work the same with the Arduino Mega instead?
I guess Iâd have to somehow confirm that the motor wiring harnesses match the Mega pins.
Iâd rather just switch out the Makermade electronics for what is more commonly used if that ultimately saves me calibration headaches. I need an accurate machine at as large a size as I can get and there just doesnât seem to be any documentation on how to calibrate the M2 yet.
My guess is yes, but I donât know for sure if MM has twisted some wires. They should be coloured and run from one plug to the other without change in order. If you can confirm that, you are good to go with a Mega, but the motor-shield will not match (as for my little knowledge) , aim for a TLE 5206 (yes, end of life, but if you can use it for 20 years, who cares).
The âchipâ on the motor shield that drives the motors. It is not continued in production, so this shield is not going to be available for long. The TLE shied has a separate âchipâ for each motor, as compared to the original shied where the left motor and the z-axis have been on a âdual-chipâ.
The origin of the Due approach has given all detail to calibrate, but not being someone to mess will PID, itâs up to MM to provide a user friendly dialling in to accuracy and before claiming âmore accuracy?â.
A very good hearted Friend has sent me a TLE9201 shield, did not try it yet, not even said thank you, different story. I did not check the EOL for this chip, might be worth looking into.
In my opinion, the best solution would be to integrate the Maslowâs kinematics model into the M2 firmware. It doesnât really seem complicated and I think it would take less than a hour for someone to do. Holey calibration could be broken out of webcontrol as a separate script/application fairly easily as well (probably more than an hour of work though, unless youâre a real programmer that knows what you are doing) so that it could be run to generate the calibrated values to enter into the M2âs settings. More advanced work would involve a holey calibration plug-in for CNC.js⌠itâs certainly doable.
I do not have the design of the TLE9201 board. Looking at the âCommits on Aug 10, 2019â in Comparing v1.26...master ¡ MaslowCNC/Firmware ¡ GitHub it is recognised by the Maslow Firmware v.1.26.
Can someone confirm that this change made it to the âHoley Firmwareâ used by Webcontrol?
The advantage of the board seems to be âover current detectionâ that is however not implement yet.

TLE9201 over-current/over-temp alarms
Note that in normal operation these alarms are often triggered by
abrupt direction change. Until acceleration control is available,
the alarms arenât useful.
Acceleration control could benefit from monitoring the S0x inputs, however.
Iâm currently working on the TLE9201 and waiting on a few boards to test on - just something to solder the icâs on. I will post the design once finished.
I didnât know the webcontrol firmware was supporting the 9201 already, I ordered the pcbs encoded as v1.6 but unfortunately I was working on the official firmware which returns -1 so I encoded them as 000111 also my pin out are complete different. Not a big issue since itâs just a prototype, on the final version I can match the webcontrol pinout.
Iâm also testing a v1.5 which is a thru hole based on the TB6643, I like the thru hole because are easier for users to make their own. Other big advantage of the TB6643 is that can be properly cooled in contrast to the 9201 that Iâm having hard time finding a heatsink.
I donât think it matters to âwebcontrolâ (i.e., the web server part) the type of board connected, as long as the string returned is something parse-able. What matters, however, is that the firmware that included in webcontrol supports the 9201, and looking at that firmware it appears it does (not sure when/who added it⌠but cheers!)
Thanks for the idea, I have a few of those as well, but donât like the glued on type, they tend to fall off, the chips can get very hot under the ârightâ circumstances
