Mach4 General Discussion / Re: Smooth Stepper Ethernet + Mach4, where am I wrong?

« on: March 11, 2021, 10:29:56 AM »

I forgot to say that at low values of Feed (1500/1800) everything works fine.
automatically comes to think of two things:
1- wrong frequency setting.
2- poorly suited or insufficient hardware for Mach4.
From what I understand, Mach4 is powerful as software and requires high performance hardware.
I sincerely hope it is the first cause.
At the moment my finances are all busy completing the new CNC.

Waiting for some answers, this morning (I'm Italian, we have a different time zone, I also use a translator) I did further tests.
Look ahead value 200.
Buffer 0.18 (default value).
Frequency from 40 (default value) I went to 200.
I have loaded a 2D Feed 5000 roughing.
On linear lines, everything is fine!
When it finds the G2 or G3 bows, it sometimes takes very hard hits !!
I had to stop right away! the blows were so violent that the pantograph trembled (I don't want to run the risk of damaging screws or supports).
The computer is a gaming PC (played Tomb Raider in medium / high quality with no problems) so amply sufficient for Mach4.
In CV mode I did some tests, right now I don't remember if it was active during the tests.
I'll try making videos over the weekend, then uploading them to Google Drive.

Attention: at the first sudden click I stop the machine immediately.
If you have any videos, I will watch them very carefully!
I want to use Mach4 also on the pantograph!
I like it! and I want it!
note: I am using the Mill version on the pantograph, I don't think this is the cause.

I also tried the same gcode on the "Rosetta CNC" controller on the new cnc I'm building to see if he was the problem.
as you can see from the video I reached F6000 (mm / min) without batting an eye.

Obviously I cannot compare Rosetta with ESS.
They are two completely different hardware, even in price, (Rosetta B costs more than 1000 euros) so the challenge is not the same.
Mach4 and Rosetta have different strengths (I'm talking about software).
Mach4 Mill is more suitable for mechanical parts, where it is possible to obtain synchronisms by wire.
With Rosetta (at the moment) this is not possible. Its strengths are rotary axes, supports RTPC, virtual machine, etc. Etc.
Returning to the purpose of the post, I am fascinated by Mach4! and I absolutely want to use it on the pantograph too !!

Hi,
in fact I didn't say that the ESS works badly.
I want to understand where I could go wrong.
in the past I have made surveys for about 10 continuous hours of work without missing a beat (here I am referring to the use of Mach3).
let's start with a question.
what value do you use of "Look haead"?
Are there any videos where ESS works with a 3D relief? with good speed like F2000 / 2500? (I am Italian I use mm / min).
if i upload gcode to google drive or dropbox, would you like to upload it to the machine and then make a video?
specifying the parameters of speed and acceleration in order to put us in the same conditions?
regarding ESS frequencies I left the default ones.

Mach4 General Discussion / Smooth Stepper Ethernet + Mach4, where am I wrong?

« on: March 10, 2021, 07:31:24 PM »

Hi,
in this forum we often talk about SSE, which I currently use on the pantograph with Mach3 (it has always worked great!).
I use Mach4 on the lathe with CSMIO IP S (again super satisfied).
Since I like Mach4 a lot, I decided to use the Mill version on the pantograph as well, as SSE is fully supported.
I make a brief consideration.
I use the same computer for both the lathe and the pantograph.
Both being ethernet, I added a PCI ethernet card.
Obviously if I use the lathe the pantograph is off and vice versa.
I have been using this system for 3 years without ever having any problems.
let's get to the point.
I don't really like the SSE + Mach4 combination.
Unresponsive jogging movements, with a slight delay.
Even worse when running gcode, if you increase the Feed slide (especially in 3D files) the machine shoots very abruptly (with Mach3 the same g-codes work without problems).
I immediately asked myself this question, where am I wrong ??
I point out that I have the exact same motor configurations, pulses and parameters.
Thanks in advance for your answers.

if you think about it, in this industry it is giving and then receiving.

if I can say my opinion about it, I see exactly the opposite.
having more options, it becomes richer software, consequently the interest in it would greatly increase.
it is currently little more than the Mach3 version.
consequently the user is unwilling to migrate to Mach4.

Yes you are right.
sorry.

I was able to run M06 macros!
to be honest, I don't really like his behavior.
why do you want to measure the current cutter before the change?
example:
during the transition from tool 2 to tool 3, was tool 2 damaged or broken?
what can it entail?
can lead to incorrect calculations?
from what I understand I don't think so, because it uses the value of the called tool.
so why measure the previous tool ??
I don't understand the need for this step.
besides being useless, it only wastes time.
in Mach3 I used 2 buttons with great success.
the first was the "Probe Set"
the second "A.T.Z."
I set zero piece.
then I pressed the "Probe Set" button.
length of the current instrument detected and a value stored.
from that moment on, at each tool change I simply pressed "A.T.Z."
even though the tip broke, I replaced it, I pressed A.T.Z. and I was immediately ready and confident.
would it be possible to do it with Mach4 too?
would it be possible to convert Mach3 scripts to Mach4?
I point out that if there are spelling mistakes the reason is that I use a translator.

which video are you talking about?
posting new videos on YouTube would be of great use to expand Mach4 knowledge!
people have to convince themselves that Mach4 is much superior to Mach3!
to do this you need information!
