I did edit the speed, accel, and jerk settings. I will upload the new firmware when I do another proper test cut.
If you are feeling froggy here is what I had in there.
#define DEFAULT_AXIS_STEPS_PER_UNIT {200,200,4535.44,760*1.1} // default steps per unit for Ultimaker #define DEFAULT_MAX_FEEDRATE {9000, 9000, 150, 25} // (mm/sec) #define DEFAULT_MAX_ACCELERATION {600,600,90,800} // X, Y, Z, E maximum start speed for accelerated moves. E default values are good for Skeinforge 40+, for older versions raise them a lot.
#define DEFAULT_ACCELERATION 600 // X, Y, Z and E max acceleration in mm/s^2 for printing moves #define DEFAULT_RETRACT_ACCELERATION 600 // X, Y, Z and E max acceleration in mm/s^2 for retracts
// Offset of the extruders (uncomment if using more than one and relying on firmware to position when changing).
// The offset has to be X=0, Y=0 for the extruder 0 hotend (default extruder).
// For the other hotends it is their distance from the extruder 0 hotend.
// #define EXTRUDER_OFFSET_X {0.0, 20.00} // (in mm) for each extruder, offset of the hotend on the X axis
// #define EXTRUDER_OFFSET_Y {0.0, 5.00} // (in mm) for each extruder, offset of the hotend on the Y axis
// The speed change that does not require acceleration (i.e. the software might assume it can be done instantaneously) #define DEFAULT_XYJERK 4 // (mm/sec) #define DEFAULT_ZJERK 0.4 // (mm/sec) #define DEFAULT_EJERK 5.0 // (mm/sec)
The makita is easy as to mount and I found the blank tool mount on thingiverse but I can’t figure out how to get the STL into fusion 360 so I can edit it, does anyone know how to do it?
I just got the Makita (RT0701C 1-1/4 HP, 6.5A compact router) from Home Depot for $99. It weighs less than that stated above, it is 3lb 1oz (1.39Kg) without the unused base plate. I read that the DW660 weighs 1.18Kg on the Shapeoko forum. That is about a 7oz difference.
The Makita has a built-in speed controller from 10000 to 30000 RPM which is a pretty good range for CNC use.
One drawback of the Makita is that to use 1/8" bits it either needs a 1/4 to 1/8 collet reducer or a custom collet from: http://www.elairecorp.com/makitaroutercollets.html
The custom collet supposedly has a very good runout spec.
There are a few reasons I don’t go with that one but the biggest is how far from the axis it is going to need to be. The closer the cutting bit is to the center of the z axis (or where the X and Y cross) the better. Linear force multiplier the further out you go. So I didn’t think you could make use of all that extra power without some serious chattering. It might be rigid enough for it, I can’t wait to see how it works. If we can cram 1.5 HP on here that would be insane. But the Dewalt for $55 has more than enough power for what I’ve tried and it comes with 1/8th and 1/4 collets.
I’m looking for the link but in one of the comments someone linked a rotozip or something similar, it looked very similar to the Dewalt, same quick chuck, same handle same standoff. This would be ideal. It seemed to be available in other parts of the world.
I haven’t had a chance to test it yet, I’ve been waiting on reprinted Z parts for a better Z fit. Once I tested it I was going to make the Makita mount look a bit more attractive too! Happy to share what I’ve got though if you need it but it’s untested (apart from mounting my router, which fits great, but I never got to actually mounting it to my MP CNC).
Sorry it’s taken me ages, I’ve been staying away from home and unable to access anything. I’ve uploaded the Makita mount here: http://www.thingiverse.com/thing:1008647
There’s also a mount for an e3d v6 (which are awesome).
that’s why we pretty much have to go for the Makita
