Pdf V5 RELS schematic file added . Cheers -- John

Hi John I am trying to install your latest version RELS_V5.0n which I may add is really helpful especially the include "Tables V5h "if I can get it working ? . I completed RELS data for my lathe parameters. Not sure how to implement #include "TablesV5.h" in the sketch I get an error "no such file" in IDE

Good morning members. Please see link below, hope of interest. My good friend Dave Abbot (Myford Boy) put me onto this. Naturally before the digital age this type of oiling was fitted on most machine tools using spindles in my very long history of engineering. I also built his design of a power hacksaw, 14 years ago and it is still my main stay of cutting up bar stock. Please search You Tube if interested in any of (Myford boy) projects, His casting work is amazing and very simple. https://www.youtube.com/watch?v=x6UDVE8nvbs Thanks -- John

Hi Julian Many thanks for your rapid response and I appreciate the full post. It seems to me, and I am not an expert that there are at least 2 types of oiler systems 1) gravity "drip" for spindles etc , 2) pressurised using a more viscous oil. My mill is a pressurised type, by operating the hand pump, the oil flows along the tubes and slowly finds it?s way between the dovetail slides. So I will currently stay with what I have, if I do not like filling up the reservoir through the window, then I will get a bigger workshop. LOL Good greetings to Mark. -- John

Please see the attached video of cutting the keyways using a sub routine g code and DDCS controller. Basically the X axis is central with the bore, the Y axis is set to a finished depth. Z axis moves up and down, an increment of cut added Y to each stroke until final depth of the keyway, At that point the machine returns to home position. Typical of a actions of a slotting machine, but using a vertical mill hands off. Hope of interest. John -- John

Please see the video of the gear cutting. -- John

I have been bouncing around looking at various posts here but I can't come up with a clear picture of the status. 1. Is this a viable project to me to use 2. Where are the files and schematics? I want/need to build an ELS for my 1022 lathe, would really prefer one with Z and X. Gerrit

Thank you to new and existing members. Start your postings. any hobby is important to keep some sanity of an ever changing world. I will change the forum to suit providing it is not "house decorating" LOL Have a good weekend. Cheers -- John

Good morning members. Hoping that the reintroduction of the RELS files and photos will be of interest. I have changed this months cover photo showing the DDCS V 2.1 control box, I use a Weiss mini mill with stepper motors to X Y Z and a controlled A Axis, indexer. There are newer versions available as mine is 4 years old. Search the web if anyone is interested. This control box handles all my needs for profile milling and multi tooth gear cutting. I recently had a small parameter setting problem with Backlash control speeds, but the support of the DDCS technical guys was more than excellent, all sorted out within a week again this version I am running was developed up to 6 years ago and still get the support I needed. For those who run routers, then this system is worth considering. I am in no way sponsoring or being financially supported by this excellent Chinese based company. There is a #CNC for ease of searching this content, I hope to post more photos in this section within a few days. Hope this post is of interest, and please ask questions, -- John

Added to files RELS V 5.00n -- John

I have changed the digitalhobbyist forum cover photo. This current photo is of my control box for all RELS functions including, Straight turning, facing, screw cutting or threading, with options for finish/ or known as spring passes, taper turning INT/EXT and a angular display for indexing slotting splines or cutting keyways. The plastic box base and lid I 3D printed. I hope of interest to all our group members. Thanks John -- John

Please see files section of RELS data. I will be sending wiring schematics and photos at a later date. The arduino file is my current file, although there are more BETA version if required. The tables.h file will need to be included in the arduino sketch. Suggest you read the doc files first, I think this info will be of help and more than sufficient to digest at this moment. -- John

Changed the cover photo. I drafted and 3D printed a harley Davidson bike, approx 250 mm long. I have all the STL files and assembly sheets available. Just let me know Thanks John owner. -- John
