Thank you Alan. That is the best explanation of the compensation value on KZfaq!

Great job Alan, umpteen guys and gals have migrated to their sheds with a suitable beverage 🍵. Thanks for sharing.

Just a thought. As your moving your quill up and down (to differant heights) to take your readings any error in your tram will give you errors in your readings. Hope this makes sense. Steve.

Hi Steve Errors in the tram would reduce the accuracy of the Z axis I did check this prior to testing . I also used a plunger type DTI which was held in a collet setting the plunger on centre line.

@@enotsengineering If you look back at your video you are altering the Z axis in all your measurements. But if you've tramed the head before starting then everything will be fine. 😉

You said it was cold in the workshop, so If the temp is under 20c wouldn't the gauge blocks be under size ?
@enotsengineering4 жыл бұрын
Hi John Yes the gauge blocks are correct at 20c but the scale and machine is under 20c that's why I put the gauge blocks on the machine bed so the temp would be the same as the machine. So if the gauge blocks contract with the temp the machine should contract the same.

Have you had any problems with Banggood. One or two reported pieces missing? I ask because lm about to buy a DRO FROM BANGGOOD for my mill. Some good deals from two if not 3 brands at the moment.. Who would you recommend. Thanks

Hi The latest DRO from Banggood is better than the older ones see my review kzfaq.info/get/bejne/aqygZZamspbdk2Q.html see link with 15% off in video description

Does the correction formula have to be in mm or can it be done in inches?
@enotsengineering2 жыл бұрын
Hi Dave the correction data is In mm on my unit I would think that as most scales are metric you need the deviation in mm. You can convert inch to mm then input the correction result in mm.

very acurate dro lol if it not show correct just use scale. why not just build scale correct.if you build scale 0.001 acurate it is acurate 0.001 move cant be 0.2. it is +-0.001 LOL,but if they build scale 0.00001 acurate but linear scale is not need be acurate spacing just,but why not build it first place 0.00001 acurate then LOL if they can do acurate spacing then just do it acurate measure LOL

This is to remove angular measuring. Picture a tape measure cooked on an angle vs straight. The scales when installed are leveled and straightened off of the aluminum extrusion. Often quite long. And to build a length that Long that is rigid enough to not flex appreciably would require extream mass. Which is inconvenient for linear scales. So we compensate for the angular miss match of the scale to the machine ways. With the invisible magic of computors doing triangle maths
