Maslow #126 Checkn in !!!
I am about to re work my sled(THE TINY SQUARE ONE!), i’m on the hunt for: Rigid Router Spindle Clamp suggestions.
Can a Maslow 1, GEN 1 ver:1.26 Run the following stepper motor: 17HS2408 ( 17HS2408 NEMA 17 Compatible Stepper Motor) ?
***NOTE: Router in shop getting : full new case(#1), lead screw, clip(you know the drill!), new brushes for motor! 850 hours total run hours! ( Lifetime Warranty still working! ) but it way overdue for a bungee upgrade!
Essentially this will be a thumb finder and chisel project! while my router is in the shop!
Thanks in advance TEAM !
the maslow in general used DC motors with gearboxes and encoders, not steppers.
IT needs to have motors that are resistant be being back-driven so that it
doesn’t lose position when power to the motors is turned off.
Would a stepper motor work as a replacement for the z motor since the z motor needs to be zeroed every time and there is no need to hold position when power is off? If so, would this be more accurate? Does firmware support it?
no, the Z is the same, both in software and in the motor controller. I’ve
advocated that a stepper Z should be made an option, but so far that has not
been implemented by anyone
It would be a good option but would require some code-ninja skills. Would it require a homing sequence every power up? Would an encoder on the stepper be desired/required?
I would not look for homing (other than the same zero detection we support now).
As for homing, with the variable amount of stick-out from the bit, any homing
would be the exact same zero detection mechanism that we support now. The Z axis
doesn’t get the forces on it that the main motors do, so it’s not likely to
shift when the system if off.
thanks to 3d printers, there are a LOT of stepper based Z axis available out
there. many aren’t big enough for a full sized router, but they scale nicely and
there are heavier duty ones available fairly cheaply.
Here’s my trick
- Set the tool stickout on the router to 1.125
- Set ZERO
- From here on, if all of your tools stick out of the router at 1.125, then your Zero will always be set!.
( This causes Massive wear on the Router )
…and yes I am upgrading to the Meticulous Z Axis, and the linear guide set i ordered came with the motor !
( 3d Printer Guide Rail Sets T8 Lead Screw + Linear Shaft 8mm + Kp08 Sk8 Sc8uu+ Nut Housing + 1pc Coupling + 17hs2408 Step Motor - Linear Guides - AliExpress )
curious about the massive wear on the router… perhaps if you are cutting full depth every time. I was under the impression that the router brushes will wear out before the bearings.
Do you not have a z motor already?
The Heavy Wear were on the main body:
- The inner Groove/Slot were the guide pin runs on
- The Hole where the Lead Screw runs through, almost broke through.
Router brushes were added in because I was nice to the Service Tech, and asked for a full overhaul on my router if they didn’t mind!
Yeah I do have a Z axis motor already, …as stated, I did receive a motor when I ordered the linear set, unknowingly, and was checking with “My TEAM” ! to see if there was any hope for it !
