Use taper, intermediate then plug tap. I just use the intermediate, and then plug tap for blind holes. I resharpen the intermediate as a gun tap, or just buy one. They are often called spiral point. Reduces cutting load considerably. Tiny diamond disk on dremmel is easy to do the gun relief. (at...

This is meant to be constructive, to help you. Not laying $hit on your good work. :rolleyes: Look at this fragment of code... case 'D': num=0.00; lcd.setCursor(16,1);lcd.print(" "); lcd.setCursor(16,1); break; } Degrees = 360/num; // <----- Division by ZERO!! for case 'D' key...

As we get older, experience (might) make(s) me very wary of working on my own. Rarely get any injuries now, using CNC, lathe (all without guards). Never stand or have part of your body tangent to anything spinning. When things get ejected, they never hit you then. Most dangerous tool is now my...

Have a look at jewellery forums. I know a jeweler that uses 8000 grit. You will have to find the forum for yourself, or others might respond. There are special methods with EDM that can achieve 0.25 micron! But where will you get a machine that stable! University research stuff.

With power off, remove and support the back panel. Turn on. Some lights on drivers will be on, because the steppers are powered. That is good. Yes. Reasonably warm is normal. Hot when you are doing continuous movement. Using arrow keys in Mach3, the DROs should change. Moving various...

The link to the text editor in config page won't work for you. You will need to select the standard screen set .... view/load screens Attached is BOB schematic. You can figure out pins from that fairly easily. The schematic is correct. If the step and direction pins in XML file is wrong I will...

chrsbrbnk. You have you maths backwards. It will .003 LESS deep. Think about it?

Touch business card until you can feel it. Set display to the thickness. The for really accurate, with cutter spinning, and observing with high magnification bring it down until you can see the cut, just. or With spindle stopped. This takes longer to type than do. Doing it is under 10 seconds...

And I have one like in post #3 http://www.homemodelenginemachinist.com/f26/what-use-tool-post-grinder-who-uses-them-18538/#post191594 I finished this with it.

You turned to pot to stopped. The electronics says speed command = 0. You rotate the shaft, now speed is not zero. Back emf from the motor rotation is sensed by the electronics. You rotated it backwards. Electronics makes a poor attempt to return to zero speed from a negative speed. The...

Hello. I am new here but frequent CNCzone forum. Melbourne Australia. I have a 4 axis SX3 CNC. Very accurate. Can I help anyone. Advice freely offered. I need some cerrobend or similar. About 1.5KG. Woods metal. 70 deg C melting point as you probably know. Local quote was $95 + shipping from...
