THANK YOU very much. This build has been a real teaching/learning experience. My two visiting home Nurses that come every three weeks, helped build the computer part of the mid tower control box. ...

My idea/goal is to be able to switch a main control and drive enclosure to three different machines with different power requirements. Yes I know, only one machine can be used at a time. Because of...

1. You will need to machine the slot to fit. If you have a drill press, clamp the block to the table and take gentle bites. I've done this before.

2. You need to do that before you install the...

No. It's a pen plotter. It's made with cheap plywood, wide open nuts (un-captured), and cheap screws/motors. You need to beef it up a LOT if you expect it to be more than a plotter.

I'm sorry, I honestly don't think CNC milling/machining is for you. I don't mean this in a bad way, but before you spend a penny, you should spend six months reading all the manuals and information...

I'm running this Sandboxed as I got a message saying this site is a verified attack sight. Anyone else get this warning?

Your ways are loose and the table is cocking.
Lash in your lead screw/nut
Slop in your bearings.
You have a metric lead screw versus an inch lead screw..

My money is your gibs aren't as tight...

LMS has a sale for the high torque extended bed kit. $99. They also have an extended bed kit for the HF 10" and 12" lathes. Except for a few extra parts that are no use when CNC'ing the mini...

Bright mild steel is not the right choice. It is VERY important to use the correct steel. A2, O1... After heat treat, the cutter must be drawn back also. Drawing back is where you polish the...

trailer wheels. not for a car. For a trailer behind a car or motorcycle. How big of a trailer are you thinking of?

Stepper systems have one fatal flaw. They are open loop. BUT, BUT, BUT.... "if the system is designed properly, it will not have a problem and work quite well." No, it will work as long as...

You don't lose steps with a servo if you aren't using drivers that utilize steps! Sorry i don't use Mach. I use LinuxCNC with a PID loop taken direct off of an encoder. I CAN'T lose steps, because...

Yep, my backlash is .0015 after oversize balls were installed.

Mistakes. If you bump a stepper on a hard stop, what happens? You lose steps. Steppers are NOT a closed loop system. You lose steps no matter how much power, and you will if you start machining...

The question wasn't answered though. How much flex does the solid mount column have? Had plans to rebuild a pile of parts into a more robust mount of the flexi column, and an extension to the base...

With having b ought all three machines third hand school/buyer/you, you are SOL in the regard of an easy start up. It isn't so bad, and LinuxCNC has a brain dead install, with settings available in...

Goodness gracious girls. Lets try to get along. The bottom line with the Taig versus an X2 clone is the material they are made out of. One is cast iron with a crappy column mount, which needs to...

Getting past the drama, inside the X2 drive box is a 12v transformer and rectifier used for the tiny fan. I'm thinking it'd be an easy way to power the LED ring. I'm also cheap, so i bought the two...

My curiosity was aroused when someone on a bike forum hosed magneto ignitions. Without getting into the arguments for or against, I'm wondering how a person might add a points-less module that...

AND if you are using steppers in "your highly accurate machine" it isn't all that accurate anyway. Mariss explained on the gecko forum that if you attach a laser pointer to the shaft of your .9*...

steppers are a specially trained horse.

MORE POWER! If you want more power in a X2, get a KBLC-19PM motor driver. Can be found cheap or expensive on eBay, and really make a large improvement. Far more than a flywheel ever would. As far...

I got his CD when it first came out. Thinking dedicated set up, not one I have to set up and tear down.

I want an X2 that can tap 1/2-13. Would also like to machine SS, and do high speed of 7k or more. Looking at the way the belt drive motor mount is made, it appears a step pulley off to the side...

How do you not notice something like that? Two ways to do this.

1. Use the one good screw hole to hold the parts in place, and drill new mounting holes through both in another spot. You have...

A quick change gear box for different threads isn't important with a CNC. All of the feed changes are computer controlled per revolution of the head stock. Machines that don't have a quick change...

Also needs to be mentioned, your Pattern/form needs to be scaled appropriately. Aluminum shrinks and your form needs to be corrected for this. Different alloys shrink in different ways. A pattern...

PROS

1. cheap
2. light weight
3. many have gone before you/lots of info

CONS

1. envelope, particularly the short Y axis
2. plastic gears

Simple answer is tracking error. closing the loop in hardware includes a real time tracking error. A pulse train tells a drive to 'go here." The drive starts moving and moves to "here." There is...

Are shops that cheap again? Be more prepared for 75-140 an hour.
