Got my motor installed #CNC

 

This is on my Craftsman?101.07403 12x36 Lathe.
I installed a .

Here is a :
I need to set up the automated (Processor Controlled) operations right now it operates off foot pedal
which I have not installed. The foot pedal uses a Hall Effect sensor which can be replaced with a potentiometer, I "hope" to replace it with a DS1803-10 digital potentiometer.

Then on to Spindle Speed and Leadscrews.

Hi Charlie,

The ELS was developed on the E-Leadscrew group as a collaborative effort and is 100% open source. ?In? fact it started out with a surface mount processor and single axis control with built in micro-stepper.? With much support from the group it was expanded to have two axis control including a wide variety of tapering profiles and the desire of the members to have a 40 pin DIP socket for easy replacement or upgrade.?

?

The first 50 units were sold at cost.? The rest sell for $200 to cover the cost of now more expensive parts due to a low Canadian dollar.? ?Next the LMD18245 Stepper Driver chips went up in price to the point where now far east modules cost less than the chips.? And the bottom plate can't be inexpensively manufactured anymore because the original company that made them is no longer around.? ?

?

My ELS has always been a kit for a hobby market. ?Never sold a box for it. I've come up with an innovative method of making keypad covers and legends that many of the users have made.?

?

The ELS was also designed to make it easy to move the parallel port DB-25 that attaches to a users's Break Out Board from the ELS to a PC to switch over easily to MACH3 for that occasional CNC project that needs more than the ELS.? (in fact I first tested it with MACH2)

?

I'm sure when you blow up your stepper motor driver or processor board or LCD screen that the Chinese manufacturer will replace it at no charge? ?My ELS has a lifetime warranty if you tell me how you broke it.? I replaced one where the end user smoked the traces off the stepper motor driver section after he accidentally hooked up his DC power backwards.? I sent him a new one for the cost of shipping.?

?

Given that my ELS has been around for more than a decade and that any google or youtube search creates all sorts of hits I'm surprised you think it's a commercial product or not targeted at hobby users. ?Users on the MACH CNC groups and the LinuxCNC groups are all familiar with my poduct. ?

?

Since the programmer circuit is on board anyone can download the free Microchip C compiler and modify the source code.? In fact if you were to look at the source code you'd see that one of the E-Leadscrew members even made modifications to improve certain behaviours. ?I've supported anyone who wants to make changes as it's also well documented.

?

I'm all for these different projects but I'm not fond of misinformation about them.

?

Just to add my two cents worth...

I think we are comparing two different systems here. RELS was designed to make it fairly easy for a hobbyist to construct, modify, and upgrade a system themselves with relatively little investment, other than time. ELS was designed as a commercial system that is available for sale. (I have no idea at what price, and am not looking to denigrate it in any way.)

RELS gives a hobbyist a lot of flexibility, in that he can easily alter the Arduino program to accomplish what he needs to accomplish, and to add desired features, such as the ability to cut MT tapers automatically, and to cut uncommon thread pitches. It currently used a 16 x 2 alphanumeric LCD display, a low-cost, easily available display for hobbyists. Due to the open source program, a larger display or larger keypad could be integrated, if a user so desired and had the programming and technical talents.

ELS, as I understand it, endeavors to be as complete as possible. I assume that the code is not open source. (Commercial code virtually never is.) ELS is intended to be a solution that needs only be integrated into the lathe, once purchased; the electronics and software are all taken care of. Hook up the power supply, drivers, and motors with the ELS and you're ready to go. It is not intended to be modified by its users. I think I have this right. I apologize in advance if I am wrong.

The original designers of both products have made decisions based on their different target markets. I think it's up to a user to decide if they are OK with any compromises in exchange for the benefits in the case of both products.

At the end of the day, it's up to the user. At any rate, that's my opinion.?Happy machining!

I cannot remember it was a long time ago as you say in the days of the
parallel port.
First the RELS does not use 7 segment LEDs and secondly both your system
and the ELS need button presses to get anywhere and do anything, so I
think this is a pointless discussion.
All the best

I still don't understand why any tolerates a few 7 segment LEDs when 4x20 or 2x40 displays are so inexpensive. And scrolling continuously through numeric menus. It's like being in the early 70's from a user interface perspective. ;-)

Imperial select how you want to enter in the size

Re: servo or stepper? #RELS

 

¿ªÔÆÌåÓý

I have two steppers on my Gingery lathe.? The cross slide is an old surplus size 23 with very low torque so it can't move very fast.? The Z axis has 280 oz-in.? Both run on 48V supply and external modules using the LMD18245 stepper drivers. ?

My Southbend only has a single motor on the Z axis with 2:1 driven by the internal micro stepper driver that is part of the ELS.? Also using the LMD18245s.? However, although it has more than enough torque I wouldn't mind faster motion so I am thinking of installing an AC Servo on the lead screw and moving the stepper across to the cross slide.? The SB already has a taper attachment and if I wanted power cross feed plus the telescoping X axis lead screw so I've not been motivated to add the cross slide motor.? And the ELS works so well for boring to depth which I do often that I've not needed to do it.? The LCD 40x2 display tells me when to retract and insert the cross or compound for threading and how much for each pass. ?So it's no brain work.

Hi, Ralph,
There are Constants, Feed, Taper and Thread tables all on separate tabs within the single spreadsheet "RELS_Metric_Calculation sheet_V2-33.ods". Is this what you are referring to? If not, could you please clarify what you think is missing?
