| Hi, here is a new review on a Kt1414 router from k2. I got the machine from ebay (from K2) and also ordered some upgrades. Like the aluminum table top and the 5 inch Z axis. I also ordered the porter cable router. The electronics and motors i have got from kelinginc.com And the as a main controller i use the smooth stepper USB controller Shipping: The shipping from K2 to Canada, was not nice and a lot of hassle. 350$ shipping is already agood price and the pack the router in a nice wooden box, what later can be used as a stand. The bad thing was, they use ups supply chain. And one morning i got a phone call from ups and they asked me if i had a broker ?????? No i am a private person i don't have a broker, so what can i do to get my router delivered ?? Answer: get a broker or drive 160 km down here to the air port and act as ure own broker. Great !!! So after spending a lot of money in gas and my nerves i was a broker for a day.And cleared the box at customs. So finally after another 2 days they delivered the router, since my car was to small to take it with me from the airport... The setup went smooth and the router was running in about 4-5 hours. My first notice was when i twisted the leadscews by hand with out the motors mounted, that the z axis makes some funny noise like cracking. After all setup and wiring, i started to tune the motors in Mach3 and ended up with 35 inch/M as max speed all over that will cause the motor to stall. But that s ok. What i find relay disappointing is the unsupported Lead screw of the z axis, and that the screw is almost to short and has bad marks on the end. Oh and yes its not relay straight , while turning u can see that it has a bent in it.(I will contact K2 about that,and see what they have to say about that.) The x and Y screws are fairly ok, but also not straight, but since they are supported on both sides , it does not matter so much. The home switches on the x and y are ok, but the one on z was a nightmare. When u move the axis higher than the switch, the screw what triggers the switch gets behind the switch leaver and on the way back down u can hear a funny noise??? It was the leaver from the switch what has got bend out off shape. So now to the cutting resolutes, when cutting a wood square 2 inch i end up with 2.016 with a 1/8 flat endmill with the brass adapter what K2 offers. Thats a lot of run out. But the good thing is it is constant so when i cut aluminum 6061 T6 it is the same. What would be nice to see on future models OF the K2 routers is limit switches, and a litle more detail on the lead screws. Best regards Anubisbot |

| @ your sizing problem you have to adjust your "pulses per inch" in the motor tuning. i'm using 9980 right now. i got it pretty close by just using a dial indicator. and the un supported rails do suck but they do sell a more expensive machine with them. good luck |

| Follow up, my motors are tuned fine, since i only got the frame from K2 , i have on a 1/8 step mode with the 0.1 inch per turn 16000 steps per inch. And that works fine. Now after playing around a bit more, i found that the x axis rails are the biggest problem. 1 they should use instead of 16mm 20mm like they do on the y. Or better supported rails. The worst point is when i have the router in the middle position of the x axis, and then u plunge into the stock, and can see how the rails bent, and u get nice marks on ure work peaces so u need to go with a lead in and out. And the x axis it self climes up, when moving to the right. no its not the workpiece. i checked it , its the table top for 175$. Its relay frustrating when u try to engrave pictures. But over all the machine is ok , but don't get it when u love perfection, like me. And for metal work, i will get my self a Syil X4 Mill, they dont bent out of shape. Best regards Anubisbot |

| Screws are not perfect, they have some amount of lead error. You need to adjust the steps/unit to correct for any lead error.

| on a cutting area from 12x12 inch, u dont feel so much of the screw errors. But my screws have dents in them , and grind up the nut from the inside. I hope they send me the replacement they offered. Best regards Anubisbot |
