ELS improvement

#RELS

les higgins All Messages By This Member #123 I had a single y axis ELS system with a tachometer and a hall effect magnet for the encoder. The system worked alright to a degree but was getting skipping issues. So with a great help from Richard Edwards I am going with the modified Russian ELS greatly improved and in English. Initially I was going to adopt the y axis system only but on reflection there not a lot of more work to do the? crossfeed x axis system as well. Almost finished the mechanical side using a? 600 p/r encoder geared 1 to 1 and a nema 23 fixed to the tailstock end 1 to 1 and a nema 23? for the crosslide again 1 to 1 only? the latter is a short version about 55mm long and less torque. Waiting for some more parts and meantime hopefully modifying the arduino sketch for my leadscrew? 2mm pitch and crosslide thread pitch 1mm? and the 600 p/r encoder. t The spec states? Pulses:600p/r(Single-phase pulses P/r, Two phase 4 frequency doubling to 2400 pulse . *Not sure about this should I set the encoder to 2400 in the sketch?*

John Lindo All Messages By This Member #129 Les I read from previous posts you were only interested in the manual screw cutting module.Z axis. and now you have decided to power up the X axis. Well done. With Richards guidance it will be really beneficial to do this add on. The 2 axis allows for automatic threading and facing, plus cutting internal and external tapers. Through the English firmware I have quite a few angles set in the taper module, originally called Cones, all the standard MT tapers and? up to 45 degrees, which makes a nice job on large corner chamfers when turning. Best wishes -- John
Richard #131 Given 600 lpr and a 3:1 drive from spindle set then (if using the 74LS86 as per spec) #define ENC_LINE_PER_REV???? 1800 // Number of lines of the encoder per 1 revolution of the spindle Richard toggle quoted message Show quoted text On 20/08/2019 00:05, les higgins via Groups.Io wrote: I had a single y axis ELS system with a tachometer and a hall effect magnet for the encoder.

les higgins All Messages By This Member #134 开云体育 Thank you for your message. I got a little confused with the rotary encoder settings and bought a 600 pr one but the spec states "two phase raising to 2400 pr but Richard said I will need a 3 to 1 to bring it to 1800 so will have to get some pulleys and belt as I have geared mine to 1 to 1 Meanwhile,very interesting group Sent from my Samsung Galaxy smartphone. toggle quoted message Show quoted text -------- Original message -------- From: John Lindo <bechetboat@...> Date: 20/08/2019 05:59 (GMT+00:00) To: [email protected] Subject: Re: [digitalhobbyist] ELS improvement Les I read from previous posts you were only interested in the manual screw cutting module.Z axis. and now you have decided to power up the X axis.
