#Grbl controller 0.7 drivers

Laser is interesting due to it's accuracy but I am worried from the reflected beams. I'll be plugging them into a RAMPS board, which is cheap, and which, as an arduino Mega 2560 shield, will replace the woodpecker said in CNC PCB milling: I got a couple extra in case I accidentally burn one or two of them out.

The yet to be used trinamic drivers cost $42.50:

Not sure yet whether the new spindle will eventually produce better results or not, although it does run quieter, which is nice. My feeling is that the steel rods are a worthwhile and very easy upgrade, even though I don't have data to prove they make any difference. The 6 chromed steel smooth rods cost around $20-30 in total, including e-packet delivery. Aside from the plastic filament needed for the print (maybe $2 worth), it requires just 4 short linear bearings and a lead nut. I had to 3D print an adapter for the new spindle to fit onto the 2418. I power it with a separate, adjustable power supply, since it can go to 48v.

The spindle I'm currently using cost $34: What was the cost for the overall upgrade? Or, just get this, which goes to 24,000RPM and has water cooling already a part of said in CNC PCB milling: The main downside to that is that it would require installing an ER11 collet, and so runout might be an issue. It could also go up to around 48,000RPM at 12v. Notionally, something like: ДЄlternately, I notice an inexpensive brushless motor with a water cooling jacket already installed, for not much money: Perhaps it would be possible to buy a water cooling jacket for the spindle? That would cover the bases against even heavy duty use.
