Personally I prefer an air cylinder(s) as a counter balance. It applies a constant force regardless of position, and doesn't add a lot of mass to the system. Plus with a regulator is easily adjustable to what ever weight needs balanced.
I like to adjust the counter balanced to what ever minimizes the force required to turn the screw in either direction. This is usually takes a force about equal to the mass to be balanced. ----- Original Message ----- From: "Brent Loschen" <brent.losc...@gmail.com> To: emc-users@lists.sourceforge.net Sent: Thursday, April 21, 2016 11:17:05 AM Subject: Re: [Emc-users] Question on DM860 stepper drivers McMaster has a nice selection of 3' long springs of various OD's, wire diameters, and spring rates. They seem reasonably priced (~$5-$10) in sizes likely used for this type of application - http://www.mcmaster.com/#extension-springs/=122u4yj. I'm curious if anyone has compared moving mass (pulley/cable/mass) vs springs for counter weighting a G0704. Other than ease of implementation, space requirements, etc., any real world advantages/disadvantages of either? ie Z axis repeatability? Any thoughts on the "right" amount of counterweight? 1/2 the head weight, more/less? ------------------------------------------------------------------------------ Find and fix application performance issues faster with Applications Manager Applications Manager provides deep performance insights into multiple tiers of your business applications.
