Big Foot Laser 15w + Mana SE Acan Module
I have a new project and would like to listen any suggest or opinion about this.
LASER engraver/cutter with 8000x8000mm
Motors NN Motor
Mana SE board
ACAN Laser module with 15W (max), Normal 8W
- phase number 2
- <stepping angle 0.9 degree
- Rated Voltage DC 3.2V
- rated current DC 0.4A
- keep torque ≥85mN.m
- phase resistance 8.0±15% ohm(20℃）
- phase inductance 9.0±20% mH(1kHz)
- turn to A-AB-B-clockwise
- rotational inertia 20 g.c㎡
- motor weight 0.14KG
- insulation grade B
Need I some modification because i'm use this type of motors?
@EleksMaker-Z can you help with firmware modification to use this motors?
@Zax do you have some expertise with this?
I removed this motors from other CNC with problens in main board. (Acan machine) This CNC with problens have an very small area to work, i need a large areas to cut wood, not to engrave. Engrave this area will be burn the laser module, i know
They are 0.9 degree, so will be half the speed of standard machine but you could change the microstepping to compensate. No changes would be required to firmware, just lower the motor current on the drivers.
But, is for cutting, so i hope that que speedy are good to cut 3mm MDF
My client need to cut parts do RC models (helicopters and airplanes), parts to use into fuselage and fiz electronics components and others related things.
Ok, in resume i can use the original mana SE firmware with this motors and original mana SE Board. Right?
Many thanks for all assistance!
You need to adjust motor driver current as these require much lower power or you will just burn out (fuse) the coils.
If you don't change the driver microstepping you will need to double the steps per mm for each axis or it will travel half distance.
The motor torque is very low, so I expect it is going to stall and lose steps.

@ianobre I don't use EleksCAM but you can easily adjust with any terminal program (UGS, CoolTerm, T2Laser).
@Zax Works fine with in tests (without laser module) in T2Laser.
In T2laser where can i adjust this configuration? (steps per mm)
Look the 1st moves.
did client request mdf for rc plane and helicopter? mdf is heavy and not ideal for rc aircarft. Balsa wood or 3mm craft plywood is better option.
At really the mdf is only for structural parts or interna structure. For fuselage and anything else, you are right, balsa is the better option.
Parts like "firewall" where the motor are fixed (airplanes) MDF is so much better.
Are you rc pilot too?
I have built a foam board RC plane, it flew great!
I flew 2ft did a flip, and hit me in the ribs.
I have a DIY DJI based quadcopter

If you are using the trial the feature is disabled, with the registered version you enable debug mode and there's a command box.
You would enter:
(this is double the normal 80 and only for your 0.9 deg stepper using the same micro-stepping as standard)
Say yes, say yes, please...
And now, the final results
- Only engraving tests ( dont consider the cutters in the wood )
- Laser 500mw (from EleksDraw )
- Works perfect with EleksCAM without any modification of software or firmware. Just Plug and Play
- In Mana SE i changed the drivers for drivers with specific configuration of my motors
- I need to fix the cables now and change the laser module for 15w module.
Is second picture mdf or supa wood? How many passes to cut through it?
@mrmister i buy this wood with the specification: MDF Natural and 3mm
This cuts has made with 15w Laser (real 8W), 80% of power 1 pass. At most os cases is necessary a 2nd pass only to release the piece the cutted part and dont leave any signal.
